My first sympton was tremor of the mouth, then bradykenisia of left arm, then atrophy of left arm, constipation and excess saliva. I also had scaly scalp & forehead. My walking was difficult and my balance was bad. I was diagnosed with PD after taking the carbidopa challenge. I am doing much better now by taking carbidopa/levodopa 25/100 four times per day. April 8th 2011 I changed to carbidopa/levodopa ER 25/100mg four times per day and after a few days adjustment I am doing alright. patientslikeme has helped me and I enjoy the support and sharing.....Napiejoe
