Try going without it for three days and see what happens - warn family members first, though, you may be irrationally grouchy.
LOL, okay, although endorphins are
released through the consumption of peppers, it does NOT cause one to become addicted to eating them, such as one will become addicted to a drug such as heroin. The "need" for hotter peppers is nothing more than what has already been expressed here, in the way that your taste buds are accustomed to the heat and you "need" a hotter pepper to feel the heat.
There is no "dependence"... No need to ween yourself off of peppers for three days, or warn your family if you do so.
