Hello, everyone. I'm new to the forums. My psychiatrist added Lamictal 25mg, on top of Wellbutrin XL 450 mgs, and Haloperidol (upped dosage to 5mgs). My doc knows how concerned I am about the weight gained on previous medications, so she added the Lamictal. Has anyone lost weight on Lamictal? I am 4'11" and down to 164 from 185 since starting Haloperidol. My meds are for schizophrenia, bipolar, and depression. I was on 1mg of haloperidol and Wellbutrin was supposed to level off any side effects. I still had bad mood swings. The wellbutrin needed a friend so I was given lamictal. Any insight to weight gain/loss would be greatly appreciated.
