I take MJ as well. My A1C is down to under 6 for the first time in my life.
There are side effects. They pretty much run the gamut, but I’ve not “suffered” many, and not too intense.
My doctor had been trying to prescribe this for me for a while now. I finally went along with it after doing some research.
The problem today is getting your hands on it. My insurance limits it to one month at a time, and I often go a week to two weeks between my last shot and the next one.
