Narcolepsy (Antifeat)

A chronic sleep disorder with no known cure. Induces major bouts of drowsiness when confronted with strong emotion and makes it hard to stay up for long periods of time.

Any character possessing this feat to has disadvantage on all Charming checks than pertain to any type of sleep (this ignores class & species immunities, resistances, and advantages).

Magical and non-magical sleep effects are twice as potent. This works for short and long rests which now regain double the spells slots and HP. Only half of your HP must be targeted to succumb to the effect of any sleep effects(includes all spells)

When using the spell Sleep(or any other sleep spell), roll 4d8 extra and add the value to the spell's targeted HP score. However, Sleep(and all other sleep based spells) now also affects you. These sleep-based spells must target you before any other creatures within range. 

Every 3 turns, use your bonus action to make a Charisma check of DC 15. If failed, you are deemed unconscious and will stay unconscious for the minimum length of a short rest. You can be woken up during this period. (This is a non-magical slumber)
