I did a three month supply and didn't feel it helped me. Maybe I needed to take it longer. And I experienced a flare up with my SFN (hands and feet). I actually started gabapentin instead 4 weeks ago...300 mg 3 times a day. I'll stick with that. I might try the Protocol again in the future. But I do have an unused 90 day supply. Paid 550.00. Will sell it for 225.00, 5 weeks old.
