To maintain your health while surviving in We Happy Few, you need food. But there will be times when only dirty and rotten foods are available, and you will have no choice but to eat them. This will cause food poisoning and affect the character's health and abilities.
Being sick while being harassed by city officials is clearly not a good idea, so you will need to heal your hero as soon as possible. To do this, you need to drink specially brewed Sick Up tea, which consists of two main ingredients: Night Glow Flower and Charcoal. you will also need an empty pill bottle.
Once you get the three required items, go to the crafting menu, where you will find the desired recipe. Create a tea and drink it - this will make your character vomit and cure food poisoning, as well as return the hero to normal abilities.
The best strategy for dealing with food poisoning is to always have Sick Up tea in your inventory. If you don't find fresh food, just eat the rotten food and drink the healing drink immediately.
