Hello I have been taking Olanapine for about 2-3 years now. When I first started olanzapine I noticed after about 2 weeks I started to gain weight, i told my mental health nurse and he said thats the olanzapine mate. Before I started taking it I weight around 80-84kgs and after about a year i went up to 100kgs and now its stabilised. Problem is I dont really want to get off the olanzapine because I feel stable now and its like the miracle medication for me, but i do want to lose weight.

How should I go about doing this? I do karate once a week and sometimes go for walks if that helps. Also I do drink beer and coke every day.
