Citalopram
"I went on this because of extreme anxiety/insomnia and it did the trick right away at 10mg/day. Be careful drinking too much alcohol. I went off it after 2.5 years and was fine for several years.
Then I lost my job and house and moved away and fell into a deep depression. So I went back on citalopram and it helped the depression quite well. After 2 years on it, I had my first hypo-manic episode which lasted 4 months nearly destroying my life. I quit the medicine midway through this period. I guess I'm bipolar 2. A few months later, severe depression started again and I went back on it. This time I could only handle 5mg/day and I was still sleeping 14 hours a day. Citalopram stopped working for me over time and probably doesn't work for bipolar 2 depression."
