I liked the Nicotrol inhaler. Before I discovered e-cigs, the inhaler was the only quitting tool that I had any success with. I would have to get a prescription from my doctor, and they were expensive, same as smoking a pack a day at $7/pack. They did have coupons on their website though. I didn't inhale it like a cigarette... I would take little puffs and let the nicotine absorb under my tongue. Trying to drag off one like a cig was largely unsatisfying. But with my method, I had the nic and the hand to mouth. The only thing missing was the "smoke". I managed to quit a few times for over a week, once for a couple of months. But it did take a load of willpower and I eventually fell back to the cigarettes.
When I got my ecig in May, it was of course, a million times better. I haven't had a cigarette in 8 months, and there is very little temptation, usually none at all. But I still keep the Nicotrol inhaler around. I have a pack of cartridges in my glove box in case of emergency, and if I was going on a long flight or somewhere else I couldn't vape, I would bring the inhaler. IMO it's the next best thing to vaping.
