Have you tried CBD oil in the form of tincture? Or RSO(Rick Simpson Oil)? I take CBD in the morning so I can function during the day and RSO at night before I go to bed so I can sleep off any THC affects it might give me. This has helped me tons and enabled me to come off from chemotherapy last October. I had a stage 3 Anaplastic Astrocytoma tumor Idh1 tumor removed in March 2015 and on Temodar for 3 years including maintenance. They saw a spot and after taking the CBD and RSO. The spot was no longer seen on MRIs. Since my last MRI in Jan. 2019 I am now out 3 months for my next one. This is a first, since my surgery, where they have been watching me very closely.
