Hungover Effect

[Streetboat]

GiveSanityBoost will give you the blue screen effect, which may seem odd as a hangover wearing off. If you want a gradual cooldown, have several areas with EntityCollideCallBacks, and have each one use SetPlayerSanity(float afSanity), going higher and higher in number. That way it'll wear off gradually, and there will be no blue flashy effect.
