Looking for some good information from the work-out folks of GT. Every time I get serious about my exercise, which usually consists of about 45-50 minutes of cardio and 25-30 minutes of lifting, I start sleeping less and less. I normally sleep a healthy 8+ hours a night of blissful and peaceful sleep. But when I start hitting the gym hard, my sleep starts getting harder and harder to come by. Last night I hit the sack at 9PM, and woke at 3:30 AM, follwing a night of some serious nightmares. This is after about 5 days of working out. WTH? How do I stop this? How do I get to both work out, and get good, restful sleep?
