Go on. How does the infection work?
You get infected and an infection icon shows with a count down. When it reaches zero it transitions to a naster infection with an orange icon. If untreated, progresses to red icon version with again another count down. When it reaches zero you die.
If you take medicine, the icon changes to a treated icon, with again, a count down timer. If medicine runs out before healed, it goes back to the nasty icon. Honey gives +1 healing, herbal anti's +2 and antibiotics +3. The nastiness per second is .75 on stage 1, so honey is usually enough to get rid of it, but not enough to cope with the more advanced stages. Medicine types stack though so if you want maximum healing take all 3.
No instant cure, but stage 1 has no ill effects. You have 1 game hour before stage 2.
I like it because all medicine is useful, you know exactly how much time you have, and some basic honey is enough early game.
Oh and certain zeds will subtract your healing on impacts that transmit further infection, so the number might move a bit if you get in a nasty fight and offset how much medicine you need to get cured.
We'll change the dysentery and broken legs to be like this as well, a timer counting down how long you have before the broken leg heals, and how long before dysentery gets worse or heals (depending if you are getting sicker or on medicine)
