I'm really glad the tryptophan helped.
Can I just warn you strongly about going on an SSRI anti-depressent. I was put on Paxil a few years ago when I was feeling overwhelmed by work and having trouble sleeping.
It was an absolute disaster! Firstly I put on three stone in six months
then when I tried to come off it I had the most terrible withdrawal symptoms. It took nearly a year to come off and pretty much wrecked my life during that time.
edited to say three stone is 42 pounds - sorry I forgot that it's a peculiar Brit unit of measurement
