The wakefulness effect of the first clause is modified here to come with a small downside, to reflect the fact that fae do not truly control the human world.
This clause can keep you awake, but only for so long. Eventually you just need to sleep or else go slowly mad. Three days is the safe limit. Every additional day without sleep imposes a cumulative -2 penalty to all rolls.
This contract also grants a +1 bonus to resist alcohol poisoning
