The hungriest I've ever been In my life!!!
I'm not sure if anyone has mentioned this to you, but it can actually take a month for the ghrelin that was already in your system to be eliminated. So it could very well be real hunger that you're feeling - but I also know that, as others have mentioned, acid can definitely fool you. If I ever forget to take my Prilosec I feel ravenous!
I'm sorry that you're feeling a bit miserable at the moment, but hang in there. It will definitely get better when you can put some actual food in your stomach. In the meantime, I would sip on water as much as you can so that you have something in your stomach.
