(m)\n\nTo repeat, the size of your sleep debt determines the strength of the tendency or ability to fall asleep. If your sleep debt is zero, sleep is impossible. If your sleep debt is very low, only a small amount of stimulation is required to keep you awake. If your sleep debt is very large, no amount of stimulation can keep you awake. \n\nThink of your sleep debt as a very heavy load. You are carrying with the help of two companions. Together, the three of you can hold it up. One of your companions is pretty strong. This companion is your biological clock. The other companion is not quite so strong, and represents transient external stimulation, e.g. noise, light, excitement, anger, pain, and so on. If one of your companions drops out, you and the other may be able to manage. If both companions drop out and you are left alone, you absolutely cannot hold up the heavy sleep debt and you are crushed. In other words, you cannot stay awake no matter how hard you try. Even without external stimulation, it is usually easy to stay awake and alert if your stronger companion, the biological clock, is helping you. \n\nWith the above image in mind, it should be clear that the things we usually assume cause us to become drowsy or to fall asleep actually do not cause us to become drowsy or to fall asleep. Their true role is to unmask any tendency to fall asleep that is present already. If you believe that boredom, a warm room, or a heavy meal causes sleep, you are completely wrong! If boredom, a warm room, or anything else seems to cause you to feel drowsy, you have a sleep debt and you need to be stimulated in order to stay awake. If you frequently feel sleepy or drowsy in any dull or sedentary situation, you almost certainly have a very large sleep debt. A large sleep debt makes us vulnerable to apathy, inattention, and unintended sleep episodes. Errors, accidents, injuries, deaths, and catastrophes can be the result, not to mention poor grades.

For the average individual that does not get it too often, the biggest cause is often stress. Acidic softdrinks and coffee can often contribue to it. \n\nHowever, some people are very prone too it and get it often. These people often have a "nervous disposition" and are subject to anxiety, high stress levels, lack of good stress management, and worrying. All of these things lead to a "fight or flight" response within the nervous system and since fighting is out that leaves the "flighty" feeling. \n\nHope this helps

regular exercise gives you lots of energy because your body gets used to having to perform. If you do not move a lot everyday, then your body thinks that no energy is needed to stay alive, and then you get really drowsy and torpid.

Its possible you aren't getting enough sleep.\n\nIts possible you aren't eating right.  Maybe you're not getting enough protein or even fat, both of which can make you feel a little more energetic.\n\nIf there's any chance you have a little depression you would not always have the energy to work out.\n\nIf you live under unrelenting stress its possible your adrenal gland has "run out of juice" and cannot produce sufficient cortisol for you to be able to exercise without feeling depleted.  ("Adrenal fatigue" causes people to feel depleted rather than invigorated by exercise.)

I used to have a similar problem in that I was always tired!\n\nChances are, you may have something lacking in your diet, or you may be suffering from the opposite of insomnia - hypersomnia. \n\nThe way I beat it was that I exercised regularly, normally in the morning or afternoon (never at night), I had a hearty breakfast and I tried to avoid catnapping. Keeping active is quite important because if you're stationary all day sitting at a computer or whatnot, you do feel tired. Even if it is taking the stairs instead of the escalator, it makes the difference. Exercise just makes you much wider awake.

U may just be a slower moving laid back person. I do know depression and anxiety use alot of energy cause your mind is really doing extra work.I take a b12 shot each month and the B complex vitamin with a meal. this helps some and a good 20 min walk each day will energise you.but dont do alot of excercise at bedtime. that will keep u awake. you might also get your blood checked for anemia

It could be Mononeucleousis = Glandular Fever\nIt could be Depression\nIt could be Chronic Fatigue Syndrome\nIt could be due to early pregrancy\n\nEither way it doesn't simply sound like you're feeling just a bit tired, it seems your energy levels and completely rock bottom even if you sleep well (oh boy afraid to say can I relate to this)...\n\n...the reasons could be several.  If due to your new medication; maybe it's a permanent side effect of them but as you are quite new to them then maybe it's just the adjusting time?  Hopefully it's that because if it is it will soon balance itself out.  Most medications make us feel tired first (antibiotics for example; when I have to take them I feel worse in first few days and completely exhausted but that's always the case, body just needs to adjust).\n\nEither way - DO talk to your Doctor about it and seek advice; help and support - as it's not easy being exhausted all of the time, it affects your quality of life in general.\n\nGood luck\n\n:-)\n\nHannah

Yes, that's why you feel tired.

Welll, it could be many reasons.\n\n1)  Do you get enough iron?  Anemia will make you really tired.  Try taking a vitamin with iron in it like One-a-Day for women, etc.\n2)  Meds may do it.  Many meds for depression and anxiety can cause daytime sleepiness.  This is a side-effect for most drugs.  Try taking your medicine at different time during the day or night.  (ie take them earlier at night so that the worst effects wear off by morning)\n3) Depression will make you tired.  BUT, do you also have negative thoughts, uninterested in other things, and the other symptoms of depression.  Only your doctor can diagnose depression.  Sleepiness does not necessarily mean you are depressed\n4) Do you have things in your life you like to do?  If you are lazy, find something.  Join a club or volunteer.  \n5)  If you are not getting any better, see a doctor, you could have chronic fatigue syndrome or anemia, or ????

It's a strange thing but sometimes too much sleep can actually leave you feeling tired, but I dunno any more than that.  Maybe you are just so rested that your body and mind are waking gradually.

You should be tested for thyroidism.  If being sluggish hasn't always been a problem for you, it could be your thyroid, especially if B12 and getting enough sleep doesn't remedy it.  Try this website to see if you have any  other symptoms: http://thyroid.about.com/od/takeathyroidquiz/index.htm

You shouldnt but you might because your body is busy digesting and sorting out good and bad, etc.  You may feel sleepy but check out how heavy the food is or how much your eating.  Food is supposed to give you energy not a need for nap (unless it is turkey and that is b/c of a chemical in it).

If you are pushing yourself too hard (working too much), this can not be good for the body. You need to get some sleep...\n\nIf you are feeling sleepy for no apparent reason, the only thing I can think of is something has happened in your life that could be making your depressed and more tired.\n\nIf neither of those are the fact, your body could probably need more exercise. it's not getting enough, or you could be eating the wrong foods....

Feeling sleepy while reading for many is due the posture in which they read. While reading a person rarely moves, this lack of physical activity causes decreased blood flow to muscles, which results in accumulation of lactic acid (a product of incomplete combustion in the cells).\n\nThis lactic acid is a highly reducing or oxygen absorbing agent, which quickly reacts with oxygenated blood. This ensures lack of oxygenated blood flowing to the brain, which makes us feel sleepy.\n\nTo tackle this problem we must avoid reading in a single stretch, instead its better to take some breaks and indulge in physical activity at short intervals.
