I had tried the e-cig once when my husband on his own decided to order me the liquid form and all the cartridges. From someone on line, I think e-bay. Anyway , I gave it a shot. I never received directions and was smoking it like a real cigarette. Dragging on it multiple times 7-8 at each time I went for a smoke. I got so sick. I had called the guy and then he advised me that I should only be taking 1 or 2 puffs. per time. That I was overdosing. That was 2 years ago. I am ready to quit and on my own order Fresh Smoke, but even though it came with directions it never does advise how many puffs would equal 1 cigarette. The cartridges are 12mg. If anyone could guide me so that I can successfully do this I would so appreciate it. I really want this to be a success. Thank You
