Sometimes it happens before I even open my eyes in the morning. Sometimes it happens a few hours later.

This has been a near daily occurrence for over a year.

My stomach feels like it does when youre on a rollercoaster and it drops. Then my mouth starts watering and I start feeling very nauseous and empty as if I hadn't eaten in days. And then excruciating pain.

It lasts for 5minutes to an hour each day. And then I'm fine.

Google suggests low blood sugar (my dad had diabetes) but my blood sugar test came back fine. It also suggests a stomach ulcer (my mother had this)

My appetite is ridiculous but this is so much more than just my normal "hunger."

I only eat once a day. Idk if that has anything to do with it, but my eating schedule has changed many times over the time that this has been happening so I don't think so.

I also struggled with an eating disorder for years during my teens so idk if that could have something to do with it either but why would I be having issues now

Help?
