"i&#039;ve just changed from risperdal to geodon. risperdal worked well for me but i put on 6kg of weight which wouldn&#039;t budge no matter what i did. i have been on geodon for a week now and the only side effect so far has been difficulty falling asleep and having a very light sleep pattern. i have counteracted this by taking a sleeping pill at night. i haven&#039;t lost any weight yet but hoping to see some results here soon."
