The sleep specialist I see prescribed Clonazapan...I think that’s how you spell it. If I participate in the three week pain program at Mayo, they said I would not be able to take this medication. I was scheduled to go but broke my foot....however, I told the staff I didn’t think I would stop the medication because I finally get good sleep. It has been so many years of poor sleep. As it turned out, I haven’t reapplied to attend the program, although my chronic pain persists.....but I always look forward to a nice night of sleep and waking up rested and ready to start a new day.....feeling grateful.
