Up until the time that I was diagnosed for Parkinson, I was able to keep blood sugar under control with diet, exercise, and diabeta. I have not changed my life style, but the blood sugar is running above 200. There are indications that eldepryl, sinemet, or cogentin do not mix. On several occasions, on awaking in the morning my eyes have been over sensitive to light, and I have vertigo. It should be noted that I take lanoxin for the heart. I should very much appreciate information and Parkison, Diabetes, and Heart Drun Drugs. Thank you. Bob [log in to unmask]
