I personally have over a dozen different eliquids flavors from different shops in my area. And yes, so of them do sit around because I'm not a huge vapor myself yet. But I do like lots of different flavors, to know my flavor palate and to know what I like and what nic levels in that flavor I can handle. If I keep them shaken up (or keep the eliquid moving) so the nic doesn't settle, do you think my eliquid would last another 4 months or so?
