i have been using msm for many years with good results and suggested to my boyfriend but when he uses only 3 drops he says it burns his lips and tongue. so after using citric acid activator I tried giving him the hcl activator and he said that burned more. wondering if any one is having this experience as I cannot understand why. I brush my teeth using 3 drops in 3 tablespoons of water and never had a problem.
