Hello Fellow Insomnia-Due-To-Stomach-Issues Person,

Don't know if I can help you, but wanted to at least commiserate.

First let's talk about you: is there any other relevant medical history you want to share? Or at least your age or any leading theories you have (you mentioned being on PPIs before, was this routine or did something happen that led to this Rx?)

My situation, maybe it sparks some ideas: Since late 2019 I have been suffering almost every night with insomnia due to stomach issues. When it started it was similar to how you describe it: "hunger", but actually more of a hollow feeling in my stomach. I was (and still am) quite into "fitness" so I was tracking my calorie intake at the time and there was no way for me to be "hungry" at night. But the confounding issues are that I have Crohn's Disease and have had parts of my intestine removed. Now the leading hypothesis is that I have a bacterial overgrowth in my intestine that causes gas to build up as the bacteria digest food, and that gas gives the same "hollow" feeling you get when you have not eaten. I have had some luck in the past taming the bacteria with antibiotics or whatever, but no solution has been permanent yet. My current "solution" is when I wake up at 4:15am (+/- 30 minutes every night pretty much guaranteed), I just force myself to eat my breakfast, wash the dishes, do one or two small tasks, then straight back to bed for a 1.5 to 3 hour nap. Not ideal but doing this, I've managed to claw back some control of my life. I am fortunate that my current job is flexible and allows me to work an odd schedule, but of course I am still gunning to return to a normal 6am to 10pm lifestyle.

Not sure if anything I just put is relevant to you but I am happy to help you brainstorm. Needless to say, doctors (both GI and sleep), although they have been sympathetic to my plight, have been next to useless as far as solving my problems go. Good luck.
