Totally agree. I tried everything, and then went the medical marijuana route and my life changed. Doctors can be really useless and self serving and people in pain are considered throw-aways.
My marijuana I either eat like in brownies or take a pinch and put in my tea and it works very,very well. I do not smoking it at all. Going the medical marijuana route ensures you get very high quality.
I had not slept more than 2-3 hours a night for the last 4 years before doing this. Now I regularly 7 hours+.
Seventeen years ago my oncologist told me that good quality cannabis was the best for chemo nausea.
