Well I was off Seroquel XR for a few months and took nothing else and still had those symptoms during that time frame. I just now got on Zyprexa after a hospital visit. Sorry if that sounds confusing. There was a brief time frame of a couple of months when I wasn't on any med that I still had the symptoms. Lately the severity is getting less and less. I haven't noticed anything disturbing about Zyprexa, at least yet.
