Lamictal seem to be a very subtle drug - it just kind of quietly works.
Vraylar is VERY new but it's been very successful for me. I haven't had any side effects on it, and I tend to be very sensitive to side effects. It's supposed to be weight neutral and I haven't gained any while on it.
Seroquel - yeah, the weight thing is why I tried to get completely off of it. I'm hoping that with the low dose I'm on that it will have less of an impact on my weight. I'd love to be off of it, but I like not having compulsive behaviors even more.

I hope you can find a combo that works for you.
