I hope your follow up appt went well. I had my post op follow up appointment today too. I was concerned I was eating too much- for instance yesterday morning I ate an entire serving of oatmeal. (Oddly enough I could only eat about half of it this morning). But the doc was not worried.
To help with the e water have you tried True ? I like the lemon- I believe it’s crystallized lemon - no sweetener whatsoever. They have a few other flavors. You can get it on amazon.
