I am post-op day 16, I was also feeling like a bottom less pit post-op day 12-15. Make sure you are taking enough protein and your water. I purchased some products that have protein in them and don't taste like card board, like oatmeal and pudding, which are allowed by day 14. Check bariatric choices on line and they have products for all stages pre & post op. Oh & read how people rate item for taste before you buy.... comments very honest :-)..... good luck
