I also take Mirapex for RLS and Parkinson's like syndrome...also called familiale tremors, which is hereditery. I take 1mg. at bedtime each night. The only side effect I have experienced is the dry, yucky tasting mouth in the morning, but brushing my teeth a couple of times usually takes care of the taste, and I keep something to drink on my nightstand every night. I have had great success with Mirapex, in fact I will not go without it...
