After reading the comments I can assume, lactose intolerance is like combining the effects of eating extremely hot food with extended fasting. Seams rough. But on the other hand, cheese. The second best thing You can eat. Totally worth it.
I know the feeling. I tried extended fasting a couple of times. After the third day it looks exactly as what You described. I shat on my couch the first time I tried it.
Reading the comments, do people not like self checkout? Is it another one of these American things, that baffle the rest of the world? Like grocery baggers. I'm European, living in Poland and Denmark and if given the choice, I will always pick the store with self checkout. It's simply faster. Only old people don't use self check out, not because of boomer ideology, but because they need the cashier's help.
Nope. Polish doesn't have one.
