thanks!
i tried tesco's, it was worse, gone back to alpro, i'll try the light then. i've been putting it in first, i'll try last. i really want to get to grips with this, as i do feel different since stopping using cows milk, can't explain it, but i do think it was perhaps not doing me any favours.
oh, and it doesnt do it in tea, it seems to be the coffe that it disagrees with! (but i'm not keen on tea)
