Sleep problems

You might want to try melatonin. It helps regulate your circadian rhythm and can help you stay asleep at night. It's done wonders for myself and my fiancé.

It might be unrelated to your workouts. I would suggest keeping some king of sleep journal for a bit recording your workouts, caffeine intake/times, and sleep problems to see if you can determine whether it's the workouts or something else. If this doesn't improve you'll at least have something to show your doctor. Is there anything waking you up? Noises, headlights through the window, overheating, restless legs, etc?

I've always had insomnia and haven't noticed much of a change related to exercise. Melatonin helps me fall asleep, but not stay asleep. It also eventually started giving me nightmares. Magnesium helps a bit with both falling and staying asleep with no side effects that I've noticed. However, both melatonin and Mg are definitely a small push to sleep rather than say, Nyquil. I tend to avoid any OTC sleep aids because they tend to not work and/or leave me groggy in the morning.

I used to sleep pretty bad until I recently bought a new bed. I always thought my old bed was comfortable, but I guess maybe not. With my latex foam bed I wake up better and find I don't toss and turn as much. At least it seems that way since before if I fell asleep under the covers they'd end up all over my room and my pillows on the floor. Now I seem to wake up in the same position I fell asleep in.

I get this too sometimes. I might even have very broken nights for 2 nights running, but then it settles out. It would bother me if I felt sleepy during the day.

I quite like using my Garmin Vivofit to track my movement while sleeping. It's been educational and helped me realize that I really sleep better when I go to sleep early and rise early.
