Ohh I can relate! I go to sleep around 2am on school nights and about 4 on weekends. I don't think coke has TOO much to do with it for me. I've been drinking coke for a VERY LONG time and I drink at least 3 cans a day. It's an addiction to caffeine and the drink itself. I did a research essay for english class on caffeine. After consuming caffeine for a long period of time, your body will automatically get use to it. So 3 cans doesn't do anything to me but 7 will. I've done about 7 cans, a 2 litre bottle plus another half a litre in the choir class party. BOY! It affected me big time. I was so hyped up..I asked all my friends if they wanted to run around the lap with me..I was just too energetic. And then, I pulled out one of those really small bouncy rubber balls and threw it in the halls trying to chase it...omg....Try to cut on the coke. If you're as addicted as me, I know it's really hard. One thing that makes me very sleepy is....agg....crying. I know..I hate saying that I cry because it makes me sound like I'm an immature teen looking for attention. Another one, is reading. I read a really good book and just can't put it down for a long time...but I get REALLY sleepy and I get LOADS of sleep...at least 10 hours. One other one...is tv or singing. Something to kinda keep me busy but exhaust me at the same time. And a final one...is lying in your bed planning out your day or just thinking about something...but not thinking too hard! Just..something like...I wonder how tomorrow will be? or something...Pleasent dreams!
