Stim

Default value: 0 | Min value: -200 | Max value: 250

How does it increase? By consuming stimulants (such as coffee, cocaine, Adderall, energy drink, etc). Each turn it will increase by 1 point if the current stim level is lower than 0. How does it decrease? Each turn it will lower by 1 point if the current stim level is higher than 0. Effects Your movement points, dexterity, intelligence and perception will increase based on the combined intensity of the consumed stimulants. These effects are lowered if your stim level is already equal or greater than 30. The bonus to your movement points can't be greater than 40, in any case.

Your fatigue will be reduced when consuming stimulants, the amount depending on the item's stim intensity. Your sleepiness will also be reduced when laying down to sleep, based on the current stim level. All this will allow you to stay awake for longer periods of time. If for some reason you want to sleep under this conditions you'll need to consume items that increase your fatigue first.

NPCs will fear players with stim levels greater than 20, which will, in turn, lower their trust. NPCs can also be affected by stimulants, if consumed.

You can die because of your stim level:

From a heart attack if your stim level is greater than 250 ("You have a sudden heart attack!"). Of apnea if it's lower than -200 ("Your breathing stops completely.").
