I'm in the same boat! I had my sleeve 4/10 and after the weeks 1 and 2 diet I dropped something like 14 pounds in 2 weeks. I was over the moon! I just went for a non-bariatric appointment today and when they weighed me I've only lost 2 pounds since 4/20. I was losing that much when I was dieting prior to surgery. I was expecting to be dropping weight like crazy these first couple weeks.
Full disclosure, I've had some stuff I'm not supposed to yet. Both liquid and non liquid. I'm SUCH an emotional eater. And after a rough day I've grabbed a tastycake from Wawa. Again, I don't make this a habit, and usually can't eat the whole thing. Also, Before surgery I was a coke zero fiend, not so much for the taste, but the caffeine. I'm pretty much useless before I've had any caffeine. I almost fell asleep on my way to work the other day because I've been trying to be good. But I've "cheated" a few times (I'd say no more than 5 times) by getting a chai tea latte or a diet Snapple. After all these trangressions, I immediately beat myself up about it. Like full on shame spiral. That usually whips me back into shape on the food front for a bit.
I know I'm self sabotaging, but after 2 weeks prior to surgery nothing but protein shakes and then clear liquids and soup for 2 weeks after, I cannot force another shake down my throat. Also, I've tried tuna salad and got horribly sick from it. I finally got to the ricotta bake and chili, which should help, but still no "hard" protein tolerance.
I've set up an alarm on my phone to remind me to drink, but let me tell you its a second full time job trying to get the bare minimum in. I'm just getting sad and discouraged that I went through all of this and then it won't work.
