i have some whey protein mix that I bought for my son, can I drink that with my lactose free skim milk? will that be considered a protein drink for post op. I haven't had my surgery yet but want start getting my ducks in a row so to speak. what about adding fruit to them?

Sure, I used to mix my powders with Lactaid milk for a long time as my tummy was intolerant. It tasted exactly like as if I made it with milk. And yes to the fruit. The only fruits to be wary of for the first few weeks are ones with tiny seeds, or ones that are very fibrous. In fact, I'd wait for at least 3 weeks before adding fruit, but once you're over your initial healing they should be fine.
