Well, I'm not avoiding the gym, I've been going 3 times a week, and part of the reason of wanting to get up early is so I can get to the gym before work.
What i was saying is that when I go to the gym in the evening, it messes up my sleep that night and I feel really bad the next day...
So bite the bullet and get up early and go before work!
If you had a flight to catch at 5am you'd be up, wouldn't you?
