Hello, Native.
I'm sorry for the delay answering your question about what I ate after takedown. My first meal at home was a poached egg with white rice. I knew I needed the high protein and vitamin B the egg provided, and the carbohydrates from the rice to give me energy, and rice helped to thicken output. Breakfast everyday was peanut butter (100% peanut butter, no added sugar or salt) on toast or bagel, an egg, and tea. I tried to eat an egg every day for the protein and easy digestion. Lunch was pasta with olive oil, salt and pepper, or store bought pesto. A piece of baked chicken for protein. No tomato sauces on the pasta in the early days because it is acidic and I was already burning. Dinner was always fish or beef or chicken with pasta or rice. Sometimes tofu. I ate a lot of protein. Slowly I began adding steamed spinach, peeled and cooked zucchini, microwaved sweet potato drizzled with olive oil. I ate sweet potato because I think it is more nutritious than white potato. When you have high frequency, you lose a lot of nutrients so every meal has to count. When I introduced vegetables again I always peeled the skin and cooked the veg really well. No raw vegetables, no skins, no salads, no nuts or seeds in those early days, and I avoid them now, too. I avoided fruit, but reintroduced them slowly (no skins). Chew everything well so by the time it reaches your pouch it is dissolved.
I made weekly batches of chicken vegetable broth, and also made bone broth. Stored them in the fridge in Mason jars and drank one each day. I really believe the broth helped speed my recovery by keeping me hydrated and full of minerals, potassium, etc. Drank a glass of water after every BM as a way to rehydrate.
Around the eighth month after takedown I was doing really well, no more burning, no more urgency or frequency, no real issues. I only needed two courses of Cipro in the first year, I think, and never used it again. I used Metamucil three or four times (doses), but didn't really need it because I was eating soft, bulking food. Yes, it was very tough in the early weeks, and each day brought a new problem and I feared it was the new normal, but it got better. I walked a few blocks every day for exercise, even when I wasn't feeling well and wanted to cry rather than walk. Food choices, using the bidet every time, baby Zincofax in early days, and light exercise. Now I sometimes forget I have a pouch. I hope it will be the same for you, in time.
