I get something like this occasionally but I have really bad eating habits and often it's in a morning after I've been drinking, so I always put it down to my body just craving easy nutrients and actual hydration. I find milk very addictive sometimes but I always have, it's just so easy to pound a carton of milkshake and feel satiated with a bit of fat, protein, water and sugar.

No visual issues yet but I will always keep advice like this in mind. I see it a lot on Reddit and occasionally I do wonder about the normality of my eating habits sometimes.
