In Canada, the similar drug used here is zopliclone (Imovane). I have Parkinsonism, possibly atypical, and until recently I thought it was just a sleeping pill, then I tried to wean myself off it - Wow! my symptoms of PD worsened badly. I followed some of the links posted here and see that it may have been helping me without my realizing it - and mornings used to be my best time, now I can hardly move then. I am seeing my MDS neuro in 2 weeks and will ask her about it, i.e. should I go back on a sleeping pill I don't need for sleeping but for PD relief.
thanks for the posting.
