I have a friend that has been on sinemet most of 23 yrs and has weaned herself slowly off of it using liquid sinemet and slowly lowering the doses. She depends completely now on fava tincture/ fava sprout balls and mucuna capsules . Have you tried mucuna in capsules? Swansons supplement catalogue sells a capsule /easily taken that seems pretty good. Fava Sprout balls are easily made (look under last post of Aunt Bean on Four Acres to grow favas...I wrote in recipe. Just have a g6pd blood test done first to make sure you are not deficient in the enzyme to assimilate them FAVISM is rare but dangerous. Good luck to you....keep going slow to reduce the sinemet
