Hi Chris,
Well, in the beginning water is all I could stand.
As time went on I had milk, Bigelow Green tea with honey (warm)  I still can not have things to hot.  Coffee but with a flavored creamer. Gatorade, and juices came later. 
 What I really enjoyed after I was 6 months was fudge cycles.  They were great. I got the sugarless kind. They felt great on my throat and added liquids to my daily intake.
The green tea is good also for antioxidants.
I am just now able to have a drink or two now and then.  I can have a beer or two, or a mixed drink if it is milk based.  Other wise it will sting !  I may have a White Russian, Smith & Kearns, Smith & Wesson, Bailey's with extra cream.  All of these drinks are made with a milk base.
At 4 months I did a lot of oat meal to eat because it was easy to swallow.  It made its own saliva.  Ha ha!!
Take care,
Diane
