You are correct, people will believe anything works. Autoimmune Forums are full of people hoping some pill will solve all this mess. If only it was really so easy.
BTW, my mom spent $600-700 per month on TV junk, sweepstakes, psychic services and scams before we were able to reign in her checking account via a court order and POA assignment, (she also had dementia and did this just prior to diagnosis).....scams prey on vulnerable people. It is awful.
