Terrible experience. I had a similar one. Force medicated for over a month with Risperidone and Lithium. I gained over 30lbs in less than 3 months. The weight gain did not help with the severe depression and lack of motivation I felt. Getting out of bed was incredibly hard. I tapered off over a period of 6 months b/c Lith and Risperidone are highly addictive despite what the "experts" say. I did it gradually, reducing Lithium by 150 each month. I was taking 1200mg. The first 5 days you will feel awful, but it takes 10 days for your brain and body to adjust to lowered dose. Stay strong. This will pass.
