I can't believe it! I finally found someone else who takes Trileptal! So you have gained weight while on it too? I think it's also affecting my vision. Whenever I up the dosage, I have blurred vision, and when I lower it, my vision improves. My doc doesn't think it's the med, but I do. I called the manufacturer and they said blurred vision is a side effect. That's one reason why I'm trying to reduce it---to see if my vision will improve. So you do take an SSRI with it? I think I need to get a new doc because he will not let me try an SRRI with the Trileptal---and I think it would help. I know I can't take one by itself, but with the stabilizer, it should be o.k. Have you noticed a change in your vision?
