I was was on buspar for a couple years. It really works for some people and not for others, unfortunately. You are almost maxed out at 60 mgs, so I think it's pretty safe to assume it's not doing much for you.
I started lexapro almost a year ago now, after being on buspar for two years. I was so terrified of ssri's and the side effects, that I started by taking nibbles off of a 5 mg pill, haha. By the time I made it to a whole 5 mg, I felt SO much better. I did stay on a super low dose of buspar too, as my doc thought it might help with side effects (which I had none).
