Has anyone had this sort of feeling? I experience this type of feeling when I take two to three sinemet CR (25/100) in sequence. The regular sinemet and the generic version do not cause this feeling. To me it feels like my head is filled with concrete.... I can take one and sometimes two CR's without developing this feeling. To me there is something in the CR version that seems to build up and cause this sensation.
