hi, thank you for your reply. just the info I needed. i have also found the following article from hadjivvasilou in 2010 re gluten sensitivity from gut to brain. all the testing terminology a bit confusing for me at times, but will print and take to dr and get the blood tests again before dropping gluten. when my tests came back negative previously I was quiet happy to reintroduce gluten into diet - prob not ready to accept that I am better without it. would rather 'know' for sure that I am doing the right thing - so my family don't think I am making it up. PN is hard for other people to understand as it is. not to mention diet - my parents still don't understand fructose malabsorption well ( me and my 8yo dau and 6 yo son all have it). will bite the bullet and try gluten free again - just have to get my head around it and try for a good year. thanks again. tambo.
