I don't eat after 6pm. I always wake around 2 - 3am to go pee. Sometimes that will cause my stomach to start gurgling and within 10-15 minutes I'm simultaneously vomiting and defacating. Recently I discovered that immediately taking Pepcid (or Tagamet) at the first 'gurgle' will stop the double ended expulsions from starting, but I'm left feeling quite crappy (but not as crappy as when I go through the whole vomiting/defacating thing). Why would walking to and fro bathroom in middle of the night cause that? I thought it was because I would have a sip of water -- but I stopped doing that, yet it still persists. The only weak pattern I've discerned is eating more carbs on those days. Any ideas / similar experiences?
