the inmate who has a pizza slice also has the pizza delivery phone number, it's 52517 and after ordering on the next day the pizza slices are in the mail-cart in the main hall, it also comes with free soda and a coupon, each slice gives a perma + 1 health..

drinking rubbing alcohol will give you 10 max health for a few hours. Also bonding with Robert upgrades game perks so with that Mushroom bros upgrade has it you gain 10 max health for a few hours when eating a mushroom.
