What Is The Effect Of Levodopa On Body Over Long Term Usage?

thank you for the follow up to my questions on my medical misdiagnosis of early onset parkinsons disease 19 years ago. my concerns are not that my original diagnosis was wrong but that nineteen years went y and the Dr. never ever said wow she is still functioning and took the time to reevaluate. So now I am basically on the minimum dosage of pills and am ready to try to eliminate the ones I do not need. last year I was taking 10 pills a day of the drug levodopa (yellow oval pill) after the levodopa challenge when we found out I really didn t need them , I took 3650 of them last year and 36000 over ten years. what is the side affects to my body
