Thanks for your reply, shadow2000. I appreciate it. I've been taking a small, occasional amount of Cogentin since early autumn. Pdoc increased my Latuda, which seems good, but I do have a tremor that has become worse. So I'm thinking of increasing my Cogentin. I hate taking yet another medication just to treat the side-effects of an initial med, so I'm hoping to get a few replies about people's Cogentin experiences.
