Yeah. this happens to me pretty often..
I used to intentionally avoid eating when I was younger [yeahyeah, I know, not healthy], & sort of forced myself to ignore the sensation of hunger.
Even now, with healthier eating habits, I tend to unconsciously tune out feeling hungry most of the time, & have to remind myself to get food. It's pretty weird how 7yrs of dysfunctionality can really dig into the psyche and program your own reactions/awareness of normal biological stimulus/needs. If I'm stressed/too immersed with immediate goings on around me/working intensely on a project, I won't realize til the end of the day I haven't had anything beyond something in the morning & coffee/water. I'm like.. ''Why's my stomach hurt? Man I feel so drained/shitty..''
But yeah, then I realize I need to eat, and I'm too damn tired to make food at that point, or when I do, I feel sick. It does go away after a little bit, if you eat slowly/drink water with it.
I try to keep little things around [or carry with me] like granola bars or apples, which helps, and keeps me from completely murdering my metabolism.
Might be a good habit to try to get into, chickens.
And take a multivitamin w/breakfast, woman!
