Found a really informative page about Melatonin tonight:
http://www.umm.edu/altmed/articles/melatonin-000315.htm So for the first time in a while I had a really bad insomnia attack last night. I woke up yesterday at about 3pm. I got a little depressed around midnight, drank a whiskey sour, still couldn't sleep. The usual 3mg dose of melatonin wasn't cutting it but I didn't want to take anymore. I finally fell asleep at 1pm this afternoon and slept until almost 8pm.
I'm thinking of starting a new blog just for DSPS and melatonin related information.

Good night, and good luck (sleeping, that is!)
