CBD did little for me. I've been on Benzo's for decades (off and on--am able to take short vacations from them for a couple of weeks up to several months), but even with an excellent diet (for me), lots of exercise: walking a half hour/day, 20 to 40 minutes of tai chi daily, and trying to play tennis again--at least able to give lessons, and having some luck in fighting off insomnia, I seem to be able to maintain: PD seems to remain at a plateau. I did realize that the tremors I'd been having for the past twenty or so years were pretty much related to social phobia. The only PD-related med' I'm currently taking is Benztropine Mesylate (brand name); Cogentin (generic). I take 2 mg at bedtime. It began working within a few weeks. I still wish that the VA or any doctors in Calif would prescribe at the very least 0.5 mg of Alprazolam or Clonazapam. I often get anxious when I know that I'll have to join in an unfamiliar social event. I'm 75 yrs old, not going to OD on the smallest dosage available, and if I didn't need to be around to care for my wife, I likely would have committed suicide when my cognitize decline began several years ago.
