In this game called The Evil Within 2, the guy you play as can drink freshly brewed coffee to heal his injuries. That's not too odd in these sort of horror games. Some had you eating biscuits or drinking energy drinks, but it's unusual to "heal" that way! Isn't it?

I find my face tingles if I drink too much caffeine. Maybe I'm sensitive to it. Or it could be high blood sugar, or just general anxiety. I've heard that stimulants worsen anxiety. Professionals always recommend you stay off caffeine, sugar and booze if you have issues with being nervous, although sugar is everywhere.

Unfortunately, I think they are deliberately addictive so people don't easily give them up entirely. Fruit juice may be a healthier choice, but fructose is still a type of sugar. Orange juice can be as bad as regular colas. Concentrated orange juice tastes off to me. Tropicana is the best brand.
