I've been challenged with the monumental task of downing 15 THOUSAND calories funnel style every single night before bed for 5 days straight. I load up a blender full of weight gain powder, oil, butter, whole milk, heavy cream, peanut butter and nutella to get the most caloric shake I could dream up and get down into my gut. Follow the journey over a week, and see how it ends up :) Tons of struggle, burping, messyness, and gluttony.
