Hello! I had a question. Recently, after much prompting with his neuro, my father's carb/leva dosage was upped to 25/100 three times a day. (Is that 75/300?) Anyway, since then, he and my mother (my mother moreso) complains that he is constantly drowsy. He'll take his dosage and then have to nap for about an hour or so. Is it normal for Sinemet to cause this much drowsiness and is there something he can do to counter it? Thanks, list friends! I don't know what I'd do without all of you and your experience!
