Good luck!  Our daughter went in with the same thing about a week and a half ago.  Miserable.  The hooked her up to an IV and pumped fluids in etc. . . This particular bug has been pretty tough this year, one of our local private schools even closed it’s doors for a day for a major cleaning/disinfecting because it was having over 80% of it’s students out on a daily basis.  Like you I also caught the dreaded bug, so I FEEL YOUR PAIN!!  Hope that Ash will have a quick in and out.  (and that you feel better as well)
