I was sleeved 9 years ago. I lost 110kg over the first 2 years and maintained weight at 67kg for 3 years. Then, I was put on ssri and anti psychotic meds and gained 10 kilos in the first 3 weeks. I went on to gain back 70 kilos of what I lost over the last few years. My psyc. put me on metformin to minimise the weight gain (even though I’m not diabetic) and my weight stopped going up for about the last year now. I have just come back to the community today as I recently committed to losing this weight again. I’m pleased to hear a previous comment here that says that people have lost weight on mental health meds successfully, I’m on the wagon and going for goal.
