Hunters Friend, I started using a Joye 510 (cigalike) the month before you began vaping (August 2009), and was unable to make the switch to vaping. For two years I tried and tried, but cigs always won the weekly joust. It was in September 2011 that I upgraded my hardware and raised my nic level from 18mg to 24mg. That did the trick for me - almost. About 2 or 3 months into vaping exclusively, the cravings were driving me nuts. That's when I tried WTA juice...and the cravings went away.
I haven't tried snus, but many swear by its effectiveness.
As for that "plastiky" taste/feel, I get that from cartomizers with filler material. Many folks love Boge or Smoketec cartos, but I can't stand the after taste of 'filler material'. I suspect you may have similar sensitivity.
For ME, a 32+ year habit of 2 paks/day Marlboro/Winston was broken with...
(1) Better hardware - Ego batts with Fluxomizers...or better yet - Stardust cartomizers (fiddle free vaping), and a Lavatube (for variety, and being able to 'tune in' to the best voltage for whatever flavor juice).
(2) WTA eLiquid. There are currently two suppliers of WTA, and both have excellent product. Both have let me down from time to time, by being out of stock, but both have always come through and fulfilled my orders. Vapelicious.com has great flavors (mostly PG based) with multiple strengths of WTA available. Aroma.com has great flavors (mostly VG based) with one strength of WTA available. I like BOTH vendors, but you should also know that BOTH will be out of stock from time to time.
(3) Backups for my hardware and juice...and backups for my backups.
It might help you to know I was UNable to taste much flavor from any of my liquids, until after about 3 to 4 months of being analog free. Not only did my flavors come alive, but I was no longer able to consume HOT SALSA or HOT WINGS...had to go to MILD heat, or my mouth was on fire!
(Tabasco sauce really IS
HOT! YIKES!!

)
There IS 'freedom' ahead, but each of us have to identify the hardware, flavors and optional supplements (such as WTA or snus, if necessary) to make our journey successful.
You can do this. Don't kick yourself for not making the switch immediately. Celebrate each analog you avoid. When you 'get it right', you'll eventually be surprised to notice you prefer vaping to smoking. When THAT happens, you'll be good to go, and it will come effortlessly. (If it ain't effortless, keep looking for the 'right' hardware, eLiquid or supplement.)
Good Luck!
(I'm celebrating 10 MONTHS analog free in a few more hours, and I'm STILL
amazed!
