I had a cold for 1.5 days.
After these i found painkillers and multivitamins.
I went i a house make a fire, eat and drink and wait.
I took painkillers, wait till the symbol was switching off and took the next one.
I do this game for ca. 2,5h. Result: Eat 8 pills of painkillers and 3 pills of multivitamines
But my cold isn´t go away.
