Hi Jim,
Welcome to the NeuroTalk Support Groups.
You could try reposting over on the
Movement Disorders Forum
You mentioned your doc taking you off all drugs. Did the tremors start while you were on a particular medication or mix of medications or do you mean he took you off the "beta blockers, gabapentin, and primidone" that the other doc had prescribed?
Have you figured out if there is a link between any anxiety or medications or caffeine or anything else that seems to make the tremors worse? You ask about anxiety meds so I wondered if you deal with anxiety issues.
If you see a connection with anxiety then it would be worth talking to your doctor about treatment for that (whether that be by medication or natural treatments or by cognitive behaviour therapy or both).
If the outdoor walks are helping keep that up and any other physical movements. I know there are heaps of excellent posts in the Parkinson's Disease forum about how helpful movement/exercize can be for them.
We also have a search feature here that you might like to check out.

take care there. Keep walking!
