My dosages varied from 1.25 mg to 15 mg, with weight gain on high dosages. 2.5 mg is the smallest denomination (at some point I cut the pill), so I see a point in your plan, but you can still gain weight and it you plan to stop it, you might as well stop now - stopping Zyprexa does not have to be with titration down. Your psychiatrist made an odd decision in putting you on Zyprexa since you do not have acute manic episodes.
