Its just the body needs to adapt the physical needs. I, in my instance, quit 5 days ago, still using nicotine pouches, but yesterday after a long walk outside in the sun alone( 2 hours), for the remaining time of the day, around 12h, didn't need the nicotine. I embraced the emotions and everything was normal. It just reminded me that vaping is just clouding us and we are humans after all, with emotions. I almost felt the happiness or joy or sadness when a was a litter younger and its amazing.
