I'm glad to hear the Klonopin is working quickly for you. I love my Klonopin.
I've been on Effexor for about 3-4 years now. I think it's time for me to change. I take 300mg a day and still feel depressed. As far as side effects, I didn't notice any sexaul change at first but over the years, the drive isn't really there. Gaining weight I haven't noticed at all. I wish you luck.
