I am currently restarting Lamictal for my bipolar disorder. I was on it for about a year and gained 15lbs. I started feeling very depressed about my weight. I was very fatigued and would take naps every day and sleep all though the night. I didn't have a whole lot of energy. My husband and I are wanting to have children so I discontinued Lamictal for the reason and because I thought it was making me depressed. However, after having Lamictal fully out of my system I realized that I was having a depressive episode that got worse because I wasn't on my Lamictal. I am not starting Lamictal again and I am going for a higher dosage now since I am in a depressive episode. As far as weight gain goes, my doctor is also putting me on Topamax which I start this evening. It could possibly counteract the weight gain issue.
I am also on a vitamin regime to help with my mood and Clonazepam for anxiety attacks.
