My wife started with 1/2 tablet three times a day at her doctors recommendation. When we contacted her doctor about side effects the doctor increased the carbidopa thinking it would help with side effects. She then starting taking 1/2 tablet 3 times a days of the Carbidopa/Levodopa and also 25mg of carbidopa three times a day. the side effects were even worse and doctor told her to discontinue all. Her symptoms started last June 15 when she noticed something in her walking. Sometime after that she begain noticing balance issues. She has always been very sensitive to medications so we informed doctor of that so she could start at lower dosage. We have been researching alternative treatments. Her chiropractor/neurologist has been treating her with acupuncture and she is also having physical therapy 3 times a week. We also heard of Gladiator Therapeutics which have products they sell which are showing some promising case studies for Parkinsons. Even with the dizziness issues, she still is staying physically active with workout classes etc.
