"i will start off by stating i am a pharmacist so i have some additional knowledge to back my statements but also am on geodon 100 mg total daily dose. first off, you must take with a meal (at least 400 calories) or else you&#039;re only getting about 40% of your dose. secondly, it can cause drowsiness (or somnolence), however, i did not experience that myself. also, you must be on a pretty solid dose to treat bipolar 1 so slowly increasing may be necessary to prevent side effects, and if that&#039;s the case you must be patient. it did take me a few days to get up to a dose i could tolerate and that did mean some extra days of hypomania, but it was worth it for the relief i feel now."
