I've been battling constant hunger also and am like you, 7 weeks out. However, I know for a fact mine is acid as I am familiar with this feeling from before I was sleeved. It feels like hunger pains, my stomach is growly and feels empty. I am not having any reflux with it, however. No heartburn or indigestion. I was taking Omeprazole OTC since the week before surgery, however I found it wasn't doing a lot for the growling as well as I don't really want to continue taking a med that is supposed to be time limited. So today I bought some generic zantac and took one and it seemed to quite my stomach (and my hunger) significantly. It didn't completely take care of it but I will take another tonight and am going to give it a week and see how it does and if necessary, I'll up the dosage since I know taking 150 mg 2x a day is just fine because I've done it at a Dr.'s instructions on and off for many years. Hope my feedback helps some. Oh! And I'm doing between 700-900 calories daily but losing super slowly. (or at least it seems like it. )
