Do you feel unhappy still?

Hmm well it takes up to six weeks to start working, but it's been two months so you would probably see at least some negative or positive effect. I also find it hard to tell because I can't remember what it felt like off of it day to day..I guess unless I was severely depressed which I guess I haven't been often.
I would suggest giving it one more month and if you still feel like it's not working for you tell your doctor you'd like to try something else.
