Brain Bleach is recommended by some as a cure for insanity and/or headaches caused by reading and/or seeing bad fanfiction. However, though most studies of this substance have shown a marked increase in the peace of mind of individuals treated with Brain Bleach, there have, as yet, been no noticeable decrease in insanity among the said individuals. Though research suggests dangerous byproducts.
