This is my first post and I'd love some help. I've been smoking for over 50 years and I'm sick and tired of smelling like an old ash tray, freezing outside (I don't smoke in my houe or in my car), and being looked at like a leper. I bought Blu Premium 100's starter pack and also the Blu white starter pack (because I like the look of the old cigarettes.......old habits are hard to break.) I started out with the medium nic and found it was too weak, so now I'm on high nic (16 mg.) I still find that I am slipping back to analogs 4 or 5 times a day and really want to get totally off the darn things. Any advice on what cartos fit my Blu batteries? I really don't want to have to fill my own cartos (heck, I'm almost 70 years old and don't want to start my own lab.) Also any batteries with longer life that fit my Blu cartos? I like the look and feel of the Blu ecigs but would love more vapor. I am overwhelmed by the volume and diversity of products! Your comments and suggestions would be most welcome! Thanks!
