I often have Sunday night insomnia (that coupled with menopausal insomnia). The Sunday problem is probably due to the fact that I really don't want to go to work on Monday, but also Sunday is the day that I ride the longest and hardest. Hours after the ride, the muscles in my legs still feel twitchy.

I have used valerian capsules, but they don't always work for some reason. Celestial Seasonings Sleepytime Extra tea has valerian in it and tastes great with a bit of honey. I've gotten into the habit of brewing up a double strength cup about an hour before bed. I read, have my tea, and find myself getting sleepy within 30 minutes. Maybe it's psychological, but if it works, who cares?

I hope you find a remedy that works for you. I can empathize with what you are feeling right now.
