Change in diet or bug?

[YoureAllABunchOfBastards]

Has anyone else found that being on plan has affected them like this? I feel really odd - stomach is cramping and I keep rushing to the loo. I'm eating a lot more fruit and veg, and more yoghurt, but have done this before and not had these effects.

When I first started SW, I did suffer from belly aches, flatulence (sorry!) and I think it was definitely down to the amount of fruit and veg I was consuming cos of the fibre! Last but not least, them bloody Hifi bars give me an iffy tummy as well! I still eat them though
