just found this on google and reading with interest.
on doctors advice ive been on a elimination diet and tried gluten for the first time for 6 weeks the other day (i crumbled when i found some choccy digestives)
immediatley i had stomach cramps but had a buzz ive not had for a while. the next day i was irritable and angry. i could tell because im venting my spleen on forums and face book and had a rant at my son for no real reason, which i was not doing during the 6 weeks when gluten-free.
ill try being gluten-free again and see what happens.
