I'm currently not venturing terribly far from a toilet anywayYour dinner will be Jello at most with water until you have to start drinking the nasty purging stuff. Then your toilet will be your best friend and don't wander far from it... Hopefully your doctor is sorta close. A long bus trip could be challenging...
Lots of stops in beach toilets with signs saying watch for snakes
Dr thinks SIBO but wants to rule out ore serious (ie Huddy involvement)
