Could be I guess. Meds do strange things but it could also be a coincidence. I take Haldol when very unwell and the only side effect I get is after six days on it my vision gets blurry so I need to go off it for a few days and do it all again if still necessary. It works well for me but the vision thing makes it an impossible ongoing med. I now take Geodon for psychosis, and to prevent it.
