I'm suffering

I had some onion rings at the pub yesterday and I still feel bloody sick! They've always been my favourite food, I craved them really badly with my first and would literally eat bags of them at a time *blush* but the grease was obviously too much for me and I spent all yesterday afternoon feeling sick/bloated and they were repeating constantly. And I'm still feeling really sicky today, even peppermint tea hasn't helped! Granted the dominos garlic bread last night won't have helped, but still!
Has anyone else found things that dont agree with them now? I ate loads of chips and whatnot on holiday, but didn't have this effect, although that said they did affect me in a different way
