I'm on Lamictal and Celexa, with Xanax as needed. This combo has worked for a year - previous meds that failed include Prozac, Zoloft, Abilify, and Risperidal. I've had to up my dose of Lamictal, but overall I've had a good response to it. My only side effects are drowsiness (but that could be from Celexa, too), so I take my meds in the evening.
Good luck - I hope it has positive effects for you!
