I always get insomnia when I cycle. It sucks!! I hate trying to treat the problem with meds especially anything addictive. I have taken Benadryl when I just had to sleep and couldn't fall asleep. I don't think I would want to do that often though. I find myself getting tired in the day and if I am able, I just take a knap. If not, then I hope I fall asleep after sitting there tossing and turning for 1-2 hours.
