Early or Late In the Night....??

i sleep late at night at abt 4.its ma own fault tat i have made wrong timings n can't sleep early....

I keep going to bed late, last night I was on here at about 1.30 am and I had been up since 7.30 am. I know it can be bad for your health to miss sleep as the body does most of its healing and repairs while we sleep. So if we keep missing our sleep the body can't do essential maintenance on us and we become ill and prone to infections. I hate having to sleep but we have to so we can stay healthy.

i goes to bed about 2-3 am ..sometimes it is 4.. i know it's late , i want to sleep early but i couldn't ... then wakeup in morning about 10 am ..when there is no class in morning .. if there is class, i wake up at 8 am .. is there any way to sleep early night .. please tell me..
