Had surgery 6 days ago, mostly pain free except for the near constant deep and awful hunger pain feelings. Mentally, not at all hungry, and drinking or a little bit of pureed things hasn't helped so I don't think it's really hunger. I've seen suggestions it could be stomach acid thing but I'm doing prilosec and tums but it doesn't seem to touch it. Did anyone else experience this? How did it last or what the cause in the end?
