$4,000.00!!

Can someone give me any advice on Health Guard T18?
I have been corresponding with them about my hypothyroidism and it was recommended that I take 12 treatments which comes to $4,000.00. Has anyone out there actually spent that kind of money and been cured of Hypothyroidism?? What else really works?
I am beginning to believe that there really is no practical cure. I am eagerly waiting to hear something either negative or positive please!!
