Wake up strategies for sleepless nights

Okay, I have a few test coming up..papers due and a career change coming very soon. Anyway, i'm a bit stressed. Sometimes when I try to sleep I can't help but think about everything I need to do. I can't stop. ...it's a cycle, when I swim, i'm less stressed, but when it does creeps up on me I don't swim in he morning because i'm too tired in the morning to go, and I need to be rested for work which just makes me antsy the next day and so on. Well, I end up skipping days and days at the pool. Frustrating. Swimming in the morning is usually the only time to go to be sure I can get a spot. How can I get myself to go in the morning, how can I sleep better at night? Have any of you come up with any strategies for this? Cheers, :coffee: Eric
