Yes I used to do it all the time in Dental School during finals.  But you need to find the time to take about two or three naps during the day 30 minutes or so.

Heavens no.  Everyone has different needs as to sleep.  Some people function wonderfully on 4 - 6 hours.  Others can't feel their best without 8 - 10.  You will learn what your body requires to feel completely rested as you go - it will change as you get older.

There are a few things you can try. \n\n1) Make sure during the day you do not take any naps (even just dozing off for a few minutes can affect your ability to get to sleep)\n\n2) Avoid caffiene or sweets any time near you going to bed.\n\n3) Try getting a white noise machine. They play a variety of sounds (crickets, rain, ocean, birds etc).\n\n4) Set a bed time and go to bed at the same time EVERY night.\n\n5) Turn off all lights and make sure you are comfortable. Close your eyes and try to focus on the white noise sound. If your mind starts to wander, focus it back on the white noise.\n\n6) Get comfortable and take deep relaxing breaths. Avoid the impluse to shift or rollover. \n\n7) Finally, be patient. don't expect to be able to go to sleep right away.  At first it might take a long time to go to sleep, but if you are consistant with your bed time and these efforts your body will adjust to the schedule and you will find it easier to get to sleep each night.

I can understand from the question that you are having difficulties sleeping, you may find these tips helpful for the sake of better sleep: \n\n1. Keep regular hours. The best way to ensure perfect nights is to stick to a regular schedule. If you sleep late one morning and rise before dawn the next, you can come down with a home-bound version of jet lag. To keep your biological clock in sync, get up at the same time, regardless of how much or how little you've slept. \nTry to stick close to your usual sleep schedule on weekends and holidays as well as workdays. If you stay up late on Friday and Saturday nights and sleep-in the following mornings you may give yourself a case of "Sunday-night insomnia": You get to bed early to be bright eyed on Monday morning and try to sleep, but you can't. The harder you try, the more wakeful you feel. When travel or work throws of your routine, try to maintain some semblance of regularity. Eat your meals at the same times you normally do. Try to get some sleep during your usual bedtime hours. And return to your normal schedule as soon as you can. \n\n2. Exercise regularly. Exercise enhances sleep by burning off the tensions that accumulate during the day, allowing both the body and mind to unwind. While the fit seem to sleep better and deeper than the flabby, you don't have to push to utter exhaustion. A 20 to 30 minute walk, jog, swim or bicycle ride at least three days a week--the minimum for cardiovascular benefits--should be your goal. \nBut don't wait too late in the day to exercise. In the evening, you should be concentrating on winding down rather than working up a sweat. And don't expect early-morning exercise to have any impact on the tensions that build up during the day. The ideal exercise time is late afternoon or early evening, when your workout can help you shift gears from daytime pressures to evening pleasures. \n3. Cut down on stimulants. North Americans drink 400 million cups of coffee a day and get extra doses in tea, cola drinks (including diet colas) and chocolate. Some people seem sensitive to even small amounts; others build up a tolerance. \nIf you're a coffee lover, have your last cup of the day no later than six to eight hours before your bedtime. Its stimulating effects will peak for two to four hours later, although they'll linger for several hours more. Late-evening caffeine can make it harder for you to fall asleep, diminish deep sleep and increase nighttime awakening. \n\nCaffeine isn't the only dietary sleep-robber. Tyrosine, a substance found in chocolate, Chianti and cheddar cheese can trigger heart palpitations in the night. Diet pills contain stimulants that can keep you awake. Other drugstore drug interactions can also disrupt you nights. If you're taking any prescription or over-the-counter drugs, ask your doctor whether they may affect your sleep. \n\n4. Sleep on a good bed. A good night's sleep starts from the bottom up. You're less likely to get deep, solid, restful sleep on a bed that's too small, too soft, too hard or just plain too old. Unfortunately, we tend to get used to our old mattresses and box springs--just like a broken-down pair of old running shoes--and may not realize they've gradually been losing their comfort and support. If your bed is older than eight to ten years, use our on-line bed check to determine if it is ready for retirement. In selecting a new sleep set, follow Goldilocks' rule: Try a variety of mattresses and choose the one that feels just right for you. \n5. Don't smoke. Nicotine is an even stronger stimulant than caffeine. According to several studies, heavy smokers take longer to fall asleep, awaken more often and spend less time in REM and deep NREM sleep. Because nicotine withdrawal can start two to three hours after their last puff, some smokers wake in the night craving a cigarette. When smokers break their nicotine habit, their sleep improves drama

YOU WILL DO BETTER IF YOU SLEEP FOR AT LEAST 8 HOURS A NIGHT

You need to go into your system settings, and either turn sleep mode off so that it never goes to sleep, or change the amount of time before it goes to sleep.  Put it at much higher than 10 minutes.

Set a time you want to go to sleep and start a routine at least a half hour before that time.  Do something to help you wind down, like crossword puzzles, or reading a good book.  Get into your PJs and relax.

No cause then my work would probably make me work more hours and I am too tired to work more hours than I am doing now. Course if I could sleep longer it might have an advantage!

You sound exactly like me.  It is now 4:07 a.m. my local time, and I will probably be up another hour or so.  I just cannot get to sleep any earlier.  It stinks because I want to sleep past noon.  I have always been a night owl and not a morning person, but this is getting to be ridiculous.  I am also thinking of seeing a specialist.  I don't do well on 8 hours of sleep.  I also need about 10.  Good luck!

Drink lots of water and avoid caffeine.\n\nDim the lights, don't play on the computer or watch TV.  Just turn on the radio to something relaxing and close your eyes.
