I usually only get about 3-4 hours of sleep a night is that enough or too little?
Depends how you feel,really its good to get 8 hours
Way too little if you ask me. You should correct this habit ASAP. But I am no expert. Instead, how about listening to those who know what they're talking about. If you are really interested check this youtube link below. It did answer many of my own questions. I hope it'll help you too. Cheers.

7 to 9. I think 9's the new one because we go through 1 1/2 hour sleep cycles. For sure as long as you feel rested. But if you try a new sleep pattern it takes some time to get use to it.
If you're trying to build muscle or just work on defining muscle you need 7 - 9 hours of sleep. If you don't workout intense and do not have a stressful job It is recommended you get at least 6 hours. 3 - 4 hours is way too little. That's what crackheads get.... just saying. Anyways if you have trouble sleeping I would suggest melatonin pills. They are really cheap and it is a chemical your body produces naturally.
