Why is food so important to you that you rather take something that might have bad effect on your cognition than simply be more... careful and cautious?

Imho, it sounds bit like disordered eating. Sure, everybody has their foods they have hard time stopping eating... but to be so defensive about it "i can't stop unless something stops me" is bit... out there... me thinks there might be something... psychological behind it. Healthy attitude towards food (by which I don't mean eating healthy all the time, rather not obsessing about food, knowing when to stop and eating just enough most of the time... etc.) is... kinda important, imho.
