It blows my mind how hard it is to find basic ingredients without added sugar.

Things you wouldn't think have sugar, and are not sweet, have sugar!

Sauces, pickles, plain yogurt, it's ridiculous

Have you ever craved food? It's a drug too!

There is a difference between being hungry and needing something sweet to satisfy a craving even though you're full. The later is called hedonic hunger and is (IIUC) very similar to addiction neurologically.
