I've been on Lamictal for about ten years. It's worked pretty well for me. No rash, no sleep interruption. I can feel your pain on 1500mg of Depakote; until recently I was on the same. Definitely zombified. It was a good mood stabilizer, at the expense of all other things in life. However, I've begun to have liver damage from the Depakote and am titrating off it right now. I feel like I have my life back. With an increase in Lamictal, and an upping of Latuda, I hope life can be back to normal soon.

Good luck with your Lamictal, I hope it's a positive experience for you.
