Having MS myself i was prescribed medication from my GP which was aweful, having to take 2 before bed, and making sure once you took them to be in bed within 15 mins otherwise your legs don't work properly. Then in the morning being unable to wake up and feeling like a zombie for a good part of the day then having to do it all again that very night, i threw them away as i prefer to smoke weed as it doesn't make me feel anything like what the prescribed medication did and can get on with my life.
I wish they would just legalise it.
