I use a probiotic everyday. I eat Greek yogurt because I like it and I can get my protein. Bu****ch out as some Greek yogurts don't have as much protein as others. You can sweeten it with sugar free jam. I like it savory with cucumbers, olives or what ever. Look up tzadziki salad. there are lots of variations. Greeks don't use sour cream. I don't like very much garlic.
Anyhow, probiotics seem to help with my digestion. You should start them now, in my opinion, because they can give you a bit of stomach distress at first-maybe gas until your system adjusts.
