Down to 3 sounds great. Do you see yourself ever quitting? I'm pretty sure I won't. I need the cognitive boosts from the nicotine, and the hand to mouth makes this the only method that ever helped me quit smoking death sticks. But who knows what laws they're going to pass soon. They might make vaping a tightly reined in thing, with the tobacco companies in charge of any and all vaping. Open system vaping is what did the trick for me.
