zyprexa is notorious for weight gain. so is seroquel. dont feel guilty. my dr swore that geodon wouldnt make me gain weight but it did (eventhough it's in the group that is less prone to making you gain weight). it's how these meds work. you did your part. you noticed and took action, no reason to feel bad.  https://www.bap.org.uk/articles/antipsychotic-medication-and-weight-gain/ see? zyprexa is on top. haldol is on the bottom and it still made me hungry af. there used to be a good explanation to why antipsych does that but i lost the link.
