ok so hear me out.
Chocolate status effect: Sugar rush
Gives you increased stamina effects, but unlike other food effects, also stacks if you eat more chocolate foods.
Sugar crash: Gives you reduced stamina effects, applies when sugur rush over 1 stack ends with more stacks based on how many sugar rush stacks you had.
If you have over 10 stacks of sugar crash, your stamina rapidly drains to 0 and you fall over face first and are stunned for several seconds while your stamina refills. (immersion!!!)
