I remember my first vaping days. I got my kit on a Friday afternoon, and vaped the whole weekend; went through three 3.5ml tanks!
Monday morning at work I realized I left my nicotine pacifier at home... bummed a cig from a buddy and damn near threw up every puff and could only burn three drags before giving it back. Unpleasant experience but, I was happy to know that I could not go back to smoking!
I hope your experience is just as rewarding.. without the puking however!
