OMG, that is so ME! I'm taking prescription meds for acid, plus additional Zantac, so I don't think it's acid. I'm hungry very two hours, like clockwork. I'm 5 weeks out. I'm obsessing that I'm eating too many calories and I'm going to blow this just like every other diet. I'm eating 1,000 calories a day, including protein drinks. But I do believe this is real hunger. I have gurgling, gnawing hunger. I eat, and it goes away. I'm still on mushies, and am eating mostly protein--egg for breakfast, a protein drink, something like soup, beans or mushed turkey for lunch, an afternoon protein drink, something like a T of peanut butter in the afternoon, then more mush for dinner, and at night before bed (so I don't lie there starving) more peanut butter. I'm also drinking lots of water. I DON'T WANT TO BE HUNGRY ANY MORE!!! I feel so cheated! I thought it would be gone forever, and here I am. I've lost only 21 pounds in 5 weeks, and I'm disappointed because I was hoping for at least 5 pounds a week in this stage.
I was so glad to read your post and know I'm not alone, but I feel for you, too. I see my doc on Friday and I'm going to ask him about it then.
