Hyperhidrosis - Excessive Sweat Remedies

I started using CBD (Hemp) oil for fibromyalgia a week and a half ago. I live where the temp is 90's +. I have serious hyperhidrosis of the head and face. I would sweat til my shirt would be wet just in a few minutes of walking outside or just getting into my car. Since starting the oil, I have barely sweated. I have suffered for many years of trying everything I could possibly find or hear about to help me. Not only has it helped my pain, it has made me not panic at the idea of being outside in the heat or even using a hair dryer!
