First of all, it can be said that this is tantamount to adding insult to injury. Overeating hurts your stomach again, and you are still adding flavor to the catalyst. It hurts too much. Don't do this. The second question is, I suggest you drink it before overeating, so that your stomach will react to antidiarrheal drugs and your brain will naturally lose its appetite when it receives the protection number. You won't overeat, and you won't have a chance to overeat.
