Thanks for the replies and information.
If I look at my hands as if I'm someone else I'd call the tremor "close to severe." I keep spilling things and knocking things over. Other parts of my body tremor occasionally, but so far, nothing persistent.
I have asked my GP for Propanalol and she said something about "that's such an old medication..." Well, it might be, but I was on it some years ago and it was a good med for me. If the Cogentin doesn't help, I'll ask pdoc about Propanalol.
Speaking with my pharmacist is an excellent idea. For some reason I tend to forget the pharmacy as a resource.
So far, the only side effect I've noticed from Cogentin is that it might make me sleepy. Since I take it at bedtime, though, sleepy is okay.
WC, nope, no back-up. It's a clinic, but I'm used to seeing my pdoc every week. She told me that if I had any med issues while she's away to speak with my GP downstairs. GP is extremely reluctant to deal with psych meds. Go figure.
Since 6mg is the max dose it seems I can try 3 mg, see if that helps.
