Thanks for the input. All negative, except for one. My neurologist discounts my fears & says it works well for many of her patients, but I seem to hear mostly negative, both here on this forum & elsewhere. May be, as she claims, that those with bad experiences are more likely to report their complaints that those who are satisfied. My observation is that I know many with PD both online & in person and it seems some probably do suffer side effects (sleepy, tired, sudden blackouts while driving, cognitive, hallucinations, compulsions, etc.), but are unaware that they have problems or that they're caused by the meds they take. Since med effects are not really well tracked, it's impossible to know the truth. I would like to hear if you think it works well for you. Or if you've found anything else that works well for a severe tremor, let me know. Thanks.
