Quick answer: Drink it off. Wine removes 25–35 insanity, chocolate 20, a tavern beer 12; early on a berry pie removes 3. Sleep only clears insanity (−20) when you had the Lack of Sleep debuff — a normal night does not touch it, which is why the purple bar "isn't going down". Writing stories at the desk also lowers it by 1 per tick.

Why sleep didn't fix it
In the 100% run: "if I didn't have the tired debuff, my sleeping didn't remove insanity." Sleep removes 20 insanity only when you are sleeping off Lack of Sleep.
What raises insanity
- Digging, burying and exhuming graves
- Autopsies
- Making headstones, fences, graveyard signs and zombie collars
- Collecting honey
- Some food: Soldier's ale +20, Baked meat +10, Flesh +10, Burger +5, Sandwich +5
- Spending energy while you have Lack of Sleep (+0.5 per point)
Insanity caps at 80, which leaves you only 20 energy — see Energy.
