I started out at 18mg, went to 12, and am now down to 6. All within a month. But now it feels like I'm sucking air rather than vaping. It's not terrible, but I think I moved too fast. No irritation (attitude wise), but I'm not quite ready to give up the throat hit that has diminished. I smoked a pack of Marlboro lights a day before I quit analogs, and am interested in keeping it at around that level for an uncertain amount of time longer. Any suggestions as to what that level of nicotine would be? Curious..
