Hi John's Mom. I started my liquid diet on the last 2 days of a trip to DC with my 13 year old son's 7th grade class. By the end of the trip I was tired, sore, hungry and cranky!! Then we got stranded in Minneapolis when our flight to LA was cancelled, which made it 3 days of liquid diet while traveling. GRRRR!! It was well after midnight by the time they got us all set for hotel rooms and transportation for the 22 of us. The teenagers were grumpy and frustrated and miserable. I kept saying "Scotch is a clear liquid! I need some Scotch!!" but everything in the airport was closed. Sigh! Once that ordeal was over the rest of the week was a breeze.
Not really much advice, but I hope you had a giggle at my adventure! Good luck with your prep and surgery!
