I have 2 friends that stopped taking sinemet VERY SLOWLY over a period of months using liquid sinemet....it can be done. Both are using fava beans and extracts, and mucuna bean capsules and fermented papaya.....check into dietary supplements and foods also. Book very helpful.....Natural Therapies for Parkiinson's Disease by Dr.Laurie K. Mischley . Read and take to your Dr as a good reference for discussion. God Bless You. Aunt Bean
