Ron, I have been taking Requip for about 3 months now; currently taking 2 mg 3X/day. I've also experienced drowsiness about a half hour after taking each dose. However, in the last three weeks or so, this side effect seems to be less noticable. Maybe it just takes some time for the body to adjust. I've also noticed, as others have mentioned, a wearing off effect. It seemed that each time I increased the dosage, the Requip seemed to be very efective for a few weeks. I've been interspacing Requip and Sinemet (which I've cut down to 1/2 tab Sinemet CR 50/200 twice a day), and there were times when I actually forgot to take the Sinemet. But after about 2 or 3 weeks, the Requip seemed to work less effectively, and for shorter periods of time, and it was necessary to increase the dosage. Has anyone been able to reach a dosage which has been effective for an extended period of time? Linda Herman [log in to unmask]
