Shakes
Shakes is a status effect inflicted by heavy addiction cravings, particularly those for caffeine (at every craving if rng(8, 400) < intensity; for 20 turns), alcohol (second stage, if rng(8, 300) < intensity; for 50 turns), painkillers (at every craving, for 20 + 5 * [intensity] turns), or low-grade methamphetamine (second stage, 10% and if 2d80 < intensity; for 20 * [intensity] turns).
Shakes is also one of attack-effects of Schizophrenic trait (duration is 2-5 tens of turns) and a heavy scourge of Jittery trait owners. With Jittery, there is a chance to gain shakes for more than 300 turns when overstimulated (stim > 50, 0.4% chance and rising) and for 400 turns when close to "Very hungry" status (hunger > 80, "480.23% and rising). It is good that Jittery attacks do not stack.
Shakes can be gained rarely during telesickness.
