I can't fall asleep at night...?

I feel anxious in my legs and stuff when I lay down but my brain and eyes are dead tired. When I was in school I used to be able to fall asleep better, so why can't I now. Is it lack of regular meals? Could it be soda since I'm drinking the same amount of soda as on what used to be just the weekends? How can I fall asleep easier??

first cut out soda completely for a few days second do more during the day...run jump play swim anything to get ur heart rate up and b outside in the fresh air and third always make sure ur stomach is happy...BUT dont eat rite before u go to bed (acid reflux)
