my gym has a boot camp, but it's at 6, which is too late for me! if they had it at 5, I would sign up in a heartbeat! I am actually not even close to being a morning person...I set my alarm about 45 minutes before I really need to wake up, and then hit snooze 4 or 5 times!
I've found that if I drink enough water during the day, it helps me stay awake. I used to drink cream and sugar with a little coffee flavoring...but that is sooo fattening! I've recently started taking a multi vitamin, and I've been more alert because of that.
