i wound up getting a black dse901 today and have so far been just smoking the sample pack. ive only gotten to the medium so far tho. while it doesnt taste bad, it doesnt quite taste like a cigarette. thats why i've ordered the marlboro flavor. i also got a spiced rum just cause i like rum so much......i did hear about mixing the rum and coke flavors, but wish i read it earlier cause i dont wanna re-pay the S&H. but i've come to a dilemma. when i would smoke a cigarette i knew when i was done, and probably smoke one cig an hour. now with this thing i pretty much puff on it whenevr i realize i got it, or see it. i feel like ive been straight puffing it all day. maybee just cause i just got it and am still excited. this may sound like a dumb question, but how long of sessions do people usually vape for? "fufilling the craving" is an obvious answer, but maybee other people who smoked for many years before trying an e-cig also feel something is missing just for the very fact that you can finish a cigarette.
