I was taking Sinemet and Mirapex and gave up on the sinemet because i couldnt tolerate the smell of it.. Somehow this drug affected my sense of smell and everything i was exposed to. Coffee smelled terrible.. and even my breath had that chemical smell. One friend said he could tell if someone had pk because of the smell and im sure it was from the medication. if you look sinemet up it is called an aromatic amino acid deca... so i am only on Mirapex now and awaiting the long overdue time release version to be allowed in Canada..
