Upset stomach upset

Upset stomach upsetWas up all last night with an upset stomach. Tried to do a quick web search to figure out how to treat it --Was I contagious? What should I take? What should I eat? Google turned up junk, WebMD symptom finder was nonsensical and UpToDate was too advanced. Finally did what I usually do --called my brother the MD-- and got the answers. There's still a long way to go to find simple, reliable answers to these sort of questions online.
