I was on Trileptal and I had weight gain, bloating, major sleepiness, wobbly walking-typical side effects, but what made me change was the gas/bloating–I cannot live with that!!! I think it's supposed to help with mania, but by the time I had started it I had already majorly crashed from a long hypomania phase, but it was helping with my panic attacks. I take Lamictal now and it has been great. I've been taking it for 15 months, and it does help with hypomnia. Many people take Lamictal over many other meds and love it. Could you try this? I had side effects to work through but I like it way more than Trileptal. Best.
