>>56531179Chocolate is one of the things that can prevent you from sleeping. Maybe not as much as coffee or soda, but still bad news if you're drinking it at night, or even late in the afternoon. And insomnia can contribute to depression. And/or moodiness.
Now, I'm not saying to quit chocolate entirely. On the contrary, it can be nice in the mornings or lunch. I'm sure it'd be much nicer to be strict with your schedule rather than some online mistakes or other items of frivolity. It's through this steely self-discipline that you can exercise mastery over your own body, after all. And through your body, the world.
