This has been my third week back in the gym. I hit it mon-fri at noon for a hard 45 minutes. I am having major problems sleeping. I am taking no supplements of any kind. No drinks, etc., nothing. Caffeine intake has decreased since i started. Diet has changed very little. I probably have less stress than ever in my adult life. In other words, the workout itself is causing the lack of sleep. I got up this morning at 5am after maybe 5 hours of sleep at best. Went to bed at 10:30 tonight and laying here now at 1am without even a yawn and feel all hyped up. Luckily the lack of sleep seems to have no effect on me throughout the day. I never feel lethargic. But i know its not good in the long run. Sleep has never been a problem for me.

Thoughts?
