I have been on the protocol for three months. The first 2 1/2 on the original protocol and the last 3 weeks on 525. I have nerve pain all over from inside my mouth, to my low back and groin and down both legs.
To date there is no difference, but I have had this for 8 years and doubt that change will happen quickly, so I pledged to go at least 6 months before considering it a wash (but may be longer, we shall see)
