How long did you keep for unregular sleeping?

I've been keeping up with my unregular sleeping patterns for quite sometime. It has been going on for about a week or so, usually because I just love staying up and surfing the internet. Actually, I just slept for a couple hours earlier today because I was so exhausted from the little sleep I've been getting that I couldn't hang on any longer. For the past week or so, I've been sleeping only about a few hours a day. I have to say, internet is very addicting. It is definitely not good to have too little sleep nor too much sleep. It's not good for our system as you said. But sometimes we do it regardless, though we know it's not going to be beneficial to us. For these next few weeks, I'm working on getting myself back on a regular sleeping schedule. I go to college so these past few weeks were a little harder on my sleeping schedule with finals and all, but since it's winter break, I have some more time to work on that =]

you got to be able to find good sleep time and stuff and other stuff that contribytes but i dont really know much
