I do, Beth. I was in the hosp in March and was given Amantadine as a counter-med to fight against leg-tremors that were caused by another medicine (I cannot remember its name, I'm sorry. I'm still having memory issues from March). My personal experience with Amantadine was that after a day or so I noticed a difficulty speaking properly. I was mumbling, and complained about it during inpatient. I was told my by IP doctor that I was imagining this. It took two days of persistence to make my case that this was not something I was making up. I was able to get computer time and researched all my meds and then made my case to another doctor who was more reasonable and heard me. That is indeed one of the side effects of Amantadine, albeit one of the lesser ones.

This said, Amantadine did work on the tremors, I just couldn't deal with the side effect that I experienced. I hope that your experience is very different than mine!
