Congrats to you - I'm at 7 days as well, and no analogs after 13 years of a pack-a-day Marlboro reds. In fact, I haven't touched them after I got my 510 in and up & running last Monday, although I expected to have to ween myself off. I think you will agree this is some amazing technology that I wish I had found years earlier!!! As dumb as it sounds to have asthma and smoke, I haven't had to use my inhaler in the last few days as well. I can see why there are so many people that are passionate about this.
There are a lot of good, friendly folks on this forum as well who have given some excellent tips and advice on getting started. All us newbies sure do appreciate that.
