I can relate--yes, i feel much better at night, and on cloudy days (few and far between out here-no real rain either), I am also an insomniac...

recently found that OTC Benadryl helps me-go figure?!!-so when i feel like a kid who needs to sleep-and the whole world is closing in on me (this takes about 5 days of not having any decent sleep)--I take a Benadryl- it helps--ya gotta be careful though--easy to build up a tolerance--(((Queen of Disorder)))
