you should add in an exercise regime. studies have shown that riding a bicycle whether 2 wheel, stationary or recumbent 3x per week increases motor function. Also try light treatment therapy. There is a study out of N ew Erland on light in the red spectrum for 20 min 2x a bday is helpful..Attached is the abstract

Amantadine is a terrible drug with bad side effects that no one tells about I ended up not knowing what I was doing or who I was!

I am So sorry to hear of the issues you are having - well, you wrote this a month ago. That should have been plenty of time to see what works for you and what doesn't. I didn't do well with Amantadine. Quit it after a few wks. It made me feel all woozy especially towards the end of my work day, driving home. I had to quit it!. Besides, it didn't seem to be making me less shaky. Hope you are much better, less of or NO more dizziness. I couldn't handle that for long. I'm not sure what an anxiety attack is like - I don't want to. Hope those have diminished/ or gone. As you've heard/ready probably many times, different meds affect everyone differently - that's probably why there are so many out there to try.

I have severe anxiety attacks and am now on 2 2 mg tablets of xanax per day. I break them in half because when I take the whole 2 mg tablets I suffer from dizziness and sometimes I fall! As long as the xanax is in my system I have no problems with the attacks. When I wake up in the morning I still have an anxiety attacks and right before I go to bed I have another one! I take 100 mg of zoloft and 380 mgs of wellbutrin! I don't know what to do anymore!

Update. Anxiety medication changed to a higher anti depressant in day and no medication at night. PD medication stopped altogether for it may be causing more anxiety, weakness and tremors. He will be reevaluated 2 weeks for stopping amanditine. But his body shakes are back strong. We are trying ‘touch point’ little gadgets that help relax with a vibration-it is helping!!! Still he is weak, needs to keep very close attention to anxiety creeping in. He is way more sense tarry than I would like him to be. The Psy MD told him to take it easy a s be kind to himself and only do what he wants. He only wants to move about a mile a day.... so till he is stronger, I guess this is what it is.
Still questioning if this is PD or a LBD, or simple burnout from a stressful 4 years?
