Hi MaryFrances,
Not with me, I am a moderate drinker, I have a pint of beer or a glass of wine with my evening meal. If I am home for lunch I generally have a fruit juice rather than alcohol. I tend to go for lunch with friernds rather than dinner, and then I do have one or 2 drinks.
To the best of my knowledge it has no efffect on my meds. On the odd occasion that we hav e a celebration of somekind, then I have more but very rarely more than 3 to 4 drinks. However I have a half of beer or fruit juice if I am driving. Even with 3 to 4 drinks, I don't notice any interference with my Sinemet, and friends have never commented in any way, that I appear to be behaving in any way different.
Hope this helps, but don't go on an all night bender, having 8, saying I said it won't affect you. It will whether you take Sinemet or not
Have a good time!!
Ron
