I experienced a lot of weight gain (40 pounds) on this medication (olanzapine),
and it just added to my depression
and made me miserable
and totally unconfident. Also, although I haven't experienced a full-blown manic episode in a while, my depressive episodes have become harder and harder to cope with. I am sad and weeping for maybe two weeks every month, and it has affected my studies and my social life.
So I asked my doctor to change the medication and she suggested lamictal.
