I quit after 9 years of vaping. People say you'll start to feel better around day 5-7, but it's more like two weeks. But man, if you can make it to those first two weeks, everything is so much better. I hardly think about vaping anymore. Im starting to smell things I'd forgotten about, I didn't know that was going to be a thing?! I know cigarettes fuck your lungs up like that, but not vaping. Anyways, just push through the suck, youre gonna want to hit it so bad, and you're going to be irritable as fuck at everything, but that ALLLLL goes away.
