Eating more because losing

In the past 12 months, i've had more daily 4 figure loses than ever. (I'm still up, so far)
I've noticed that i'm also eating more on those days in the form of a sandwich in between lunch and dinner. (No lines at the casino sandwich shop)
And i wasn't even feeling hungry.

Why couldn't i lose appetite when feeling low like some other people?

If I was betting $5 (below $600), $10 (above $600), or $15 (above $1,000) on Dragon Link, I'd have a $400 buy-in and try to cash-out at $1,600. But 80 spins of buy-in may only last 100 spins and it is likely to completely lose. So I'd need to win one of every 3 sessions with a cash-out at $1,600 to stay afloat.

As for the double mushroom swiss-burger for $15, I may still have to pay cash for it because the points may not be enough.

Kuchisabishii is a Japanese word meaning eating because of "mouth loneliness" rather than hunger.

I don't know of a cure. My hunger is pharmaceutically suppressed most of the time.

Feeling low is one thing, but this sounds more like the classic "stress eating." Quite a few people I used to work with would comment that, after retiring, they started eating less because of this.
