Hi Barb, About 2 years ago I noticed a mild tremor,now and then,not always,in my rigth hand and thumb. I decided to take half the prescription of levedopa (simonet like drug) and deprenyl(seligiline) that is the minimum of the minimum amount possible,and then the tremors are no longer perceived up to now.I never suffered of rigidity though. I am 67 and do continue playing soccer and practicing other sports normally. Best wishes. Joao Paulo(John Paul) Carvalho
