I was on Celexa, for 3 months last year but it didn't do
much for me, in fact it was like i wasn't on it at all, the only bad side effect
was loss of sex drive and libido etc. no weight gain or loss that i noticed. I have bipolar 1, and was on other medication at the time. as you probably know everyone is different when it comes to these types of medication so please don't be discouraged by my comment. My dad was on it for 10 years and said it was the best thing he had ever tried for depression.
