I can't comment on your entire post, but... regarding my personal testimony of QM:
I'm a smoker.. a toker.. includes a pack a day of American Spirits.
My chronic/phlegmy cough disappeared about 1 month after steady doses of QM.
That funky cough returned about 6 months after I stopped taking QM.
Needless to say, I recently bought another bottle!
Just sayin.. that's kinda hard to ignore! And, I totally recommend QM!
I don't make many life recommendations.. but, here's my favorite if you have any lower back pain.. YouTube "McKenzie Back Method"... it's a legit game changer! Buy the book if you're serious!
