Never hungry but a sore abdomen

I'm only on day 5 with the SS, and have been coping fine, haven't felt hungry at all... but had a bit of an odd feeling yesterday.

I couldn't get home, so didn't have my lunchtime shake till a couple of hours later, and ended up with a realy wierd "sore" feeling in my upper abdomen.

Happen to anyone else?

Always always make sure you have the packs you need for the day and maybe one extra in case you get stuck and cannot get home when you originally planned. not sure what is going on with your tum though.
