ok just started vaping a few days ago and love it. now i am wondering if i love it a bit too much . i used to smoke pack a day marlboro lights. i don't know the nicotine equivalent is in liquid. i finished 15ml bottle in 3 days! does that sound too much too quick ? i don't feel any discomfort but i really want to know what is "normal" . with analogs you have a routine and defined number of cigs a day. how do you do the same with juice ?
