i am 56/8 . i started out with a low dosage of sinemet 25/100 1/d after after 3 years , eldepryl was added 2/d and i switched to sinemet cr 50/200 2/day. three years later, amantadine was added 2/d. six months ago i phased in mirapex and phased out sinemet i currently take amantadine 2x/day eldepyrl 2x/day mirapex 1/2 mg 3x/day after almost 8 years in am doing very well with little shaking apparent on my right side. the only exceptions are when i get cold or stressed. this exacerbates the shaking amantadine has been in my regimen for almost 3 years and seems to still be working well hope this helps best regards murph
