Hi there - I'm not sure where you are in Canada or what access there is to medical marijuana. Sounds as if you have an issue with both chronic pain and sleep disturbance, so a case could be made for you to be given mm. I live in BC and here we have a couple of different dispensaries where a doctor could refer you if you qualify. My doc didn't want to refer me (I have chronic migraines) but I have loads of documentation from my neurologists that state my condition and symptoms. I was able to fax one of the doctor's reports to the dispensary and they accepted it in lieu of a referal.

Basically, google "medical marijuana + your province" to find out what the process is then talk to your doctor. I would say there's no harm in trying (I got turned down by my doctor and I still have a good relationship)
