@artscaping Chris, I agree with you about marijuana. Linda, my wife, usually tries to limit herself to using it twice per week. She knows from experience that if she uses it too often it will reduce it' effectiveness. Lately her pain has just been so bad and relentless she has used it several times within a week. The other day she said she had smoked two different times (medical MJ is illegal in Tennessee) in one evening after having already used it two or three times very recently. She said it did nothing and looked quite disconsolate. I feel so badly and so helpless when she has bouts lie this. Anyway, just wanted to tell you that I agree with overuse of MJ which seems to be true with many other things as well. Best, Hank
