I have been taking Permax .25mg x 2(.50mg) plus 1 & 1/2 Sinemet at 6am;10am;2pm;6pm. I learned Permax comes in 1.0mg. Does anyone know why I can't use 1/2 of the 1mg Permax instead of two .25mg Permax at each dosing? I find it less expensive. BTW, 100 1mg at Walgreens costs $354.62. YIKES!! Jim Ryan 57/7
