And even though the analogs taste nasty and the e-cig tastes so nice, there's just something in those analogs that I just keep craving!
We can't absorb the nicotine as efficiently from vapor into deep lung tissue like we could with smoke--it's mostly only absorbed in the mouth and upper respiratory system, so the only reason to even inhale is for throat hit. If you're craving analogs, you might try kicking up the nicotine or adding menthol, otherwise some people find that using other smoke-free products like snus or dissolvables gives them the other tobacco alkaloids they crave but still avoid the byproducts of combustion.
When Camel was test marketing the dissolvables in my town, I bought one pack of the Strips to keep on hand in case I couldn't vape or was craving "the real thing", I'd pop a strip and within 2-3 minutes the cravings disappeared with the strip!

One pack lasted me for over a year and I still have one left to show people, but I keep a tin of snus around "just in case"--I never really got into the taste or experience of "chew" and usually prefer
vaping, but its nice to keep my options open. I gave myself "permission" to smoke if I really want to and I'm confident that if I won't start smoking regularly anyway--the last cigarette I smoked was just to have a date to point to because I'd forgotten so I smoked one cigarette on 12/31/09, but now I don't want to break the nice streak I've got going!
