Wine while on Decadron?

Had the decadron while on my varous chemos. Did not need the "whole" dose, so cut to 40mg. I love good wine and have a glass or so almost every night with dinner.
The decadron was with chemo so my problem was the mouth sores. My onc said I could continue to have my wine as long as I had no stomach upset (which I almost never did). I had to cut out the big reds with lots of tannin and acidity. Same for the more acidic whites. Found that wines from Alsace and Germany, as well as Beaujolais were easier to tolerate. These are also generally a little lower in alcohol.
Cheers!
