I am a 68 year old woman who was diagnosed in 2002 with Parkinsons. I have been very fortunate in that I do not have dyskinesia symptoms unless I over-med. My symptoms are mostly freezing issues. I have been on sinemet (carbidopa/levodopa) since 2002 and have had good success; however I recently went through what I thought was low blood sugar issues, so began looking for a solution. My neurologist prescribed Rytary (extended release carbidopa/levodopa) one week ago, and I can't tell you how wonderful it is to have my life back! I went from taking meds every 2 hours to every 5 hours. Because it is extended release, I sleep better with more fluid nighttime movement. I also bought John Pepper's book and am inspired what this gentlemen has asked of his body. I got back to hiking easy trails yesterday and am disciplining myself in other ways.. If you have questions about the Rytary, let me know. Above all - smile today!
