LittleAngel,
I'm new here but I have cruising through the message boards. I am a good canditate as far as certain medication firsthand, I say that because I suffer from migraines and I can relate, of course this isn't your case at this point. I was on antidepressants for depression, I looked up about anti-seizure causing facial hair I didn't find anything n your criteria, maybe you can find better luck by searching in WebMD.com. Now about weight gain anticonvulsants meds it helps you lose weight and the Wellbrutrin does help you quit smoking as the others have mentioned.
I try not to act as if I'm a professional just sharing my experience, which varies from one person to the next.
Like Dan mentioned about neurontin it is help many other conditions, for me to help prevent seizures and migraines but I was taken off it because it wasn't working. Now Cymbalta is a good drug for depression I liked it, but I had to quit taking it started to caused me to tremor, that was after taking it for about 6 months or so, I was upset that I had to stop taking it.e
The only meds that made me gain weight was Lithium for bipolar type II, it is a good drug and everything but I was so thirsty all I drank was water and nothing else, I hated the taste of coke, after going off of it, it took me a while to get used to other bevages. I weighed more I was when I was pregnant with my son (10).
I hope this finds you helps, if you have any more help I'd be glad to help you out.
Love,
Andrea Monique
