Belly Ache

One of my flat mates made me some food last night and I gladly ate it. I asked her what was in it after I had finished eating it, this was a mistake. Meat. I haven't had meat since day dot and it seems my digestive system can handle it. I've got a belly ache today and I had one last night. It's problematic because I've got things to do today and now I can't do them. I'm letting people down and consequently myself.
