I have never been tested for H Pylori, will ask the doc about that, thanks for the suggestion!
Re the LDN, I started taking a very low dose and worked up to 4.5mg. Had a couple of nights of weird dreams, but otherwise slept better on it than off it.
Blood test last week showed counts had gone down though, especially white cell count. So the LDN defo hasn't helped with that, and I have stopped it for time being to see if it makes any difference. Suspect it doesn't make much difference to blood counts, but am erring on the side of caution!
