At this point, I think it's just the "habit". I've actually started carrying my 808 auto with a high capacity LR cartomizer filled with dekang menthol for when I feel the urge to have a real cigarette. It's working mostly, except the morning time when I feel I need the quick nicotine fix. It's like my brain can't sever the tie for the AM smoke.
I've tried a *lot* of juices, too. My tongue is very stubborn. Or maybe it is at a stand still for healing as I do have one or two analogs per day. KBV, BWB, FSUSA, TastyVapor, VaporRenu, Ms. T's Bakery, digitalciggz, Liberty Flights menthols and tobacco, dekangs... you name it - I've tried a lot. I have a couple beta samples for one of the suppliers that I am hooked on, but running out of fast. Ahhh maybe I'll tell the gf to hide them... so I have to resort to vaping only.
Edit: It even got so bad one day trying a bunch of flavors that I experienced a nicotine overdose. Never passed out so fast in my life. *shudder*
