I was on lamictal. It stopped my panic attacks and my bipolar symptoms. It takes a while to get on the right dosage because of the slow titration. Trileptal is what I'm on right now but beats it if it works for me at all. I was off lamictal or like 6 months and the only problem i had was insomnia and obviously Triliptal isn't helping with that.

It's weight neutral and I can't really recall any side effects accept it can cause a rare rash, acne in some cases. It's really weird on the skin for some reason.

I'd check and see if Triliptal can help first. I was going to recommend a moodstabilizer for your panic attacks because I've had no better panic/anxiety meds than my mood stabilzers for some reason. I don't know why that is.
