i have just been prescribed lamotrigine Sandoz (lamatical) for depression / anxiety. I haven't had much success with any antidepressant medication. I'm really worried about the amount of weight gain I've read on this. As I'm in my 20's and single, any weight gain is a huge issue for me. I have a lot of trouble losing weight as it is. Also iv read it cancels out the contraception pill ?How much weight hav ppl gained on this drug and in how long ??? has anyone fallen pregnant on it ??
