I've been on risperdal 1mg along with lithium 1200mg and paxil 60mg for about three years prior to that I took 3mg of risperdal for about two years. I have had massive weight gain (100+lbs) and only recently found out risperdal can cause excessive weight gain. I've also noticed it seems lately to be sapping my energy and making me really sleepy.

Has anyone had any experience with risperdal and specifically these side effects? Any input appreciated.
