I still have an open pack of cigarettes in my car (the walk to the car has prevented me from cheating), two unopened packs in my freezer. Hard to explain but I do not think I will ever throw them out. It took me a while to stop the morning and bed time cigarette. Earlier on once or twice a month would light up a cigarette, rarely finishing it. I started with 18mg (one 10 ml bottle) of some tobacco flavor. It went into the bin rather quick. I finally got over the "I like / want tobacco flavors" a vanilla custard cured that. I really find when I have not vaped in a bit, mornings etc I really want a cigarette. After a few good vapes it goes away.
eRoll, I still love my eRoll's. I hate how often I need to fill them and the cost of the coils (be gentle with them and they will last). They are great to let other people try vaping or flavors as they are easy (pretty much idiot proof I had no issues

). Throw in a Innokin Ucan and a Joyetech eRoll Case and it makes it a little better. Battery life (PCC or ecig) will not last the day. I usually use the eRoll or eGo's for "stealth vaping".
For me others may not agree.
One does not have to do "lug hits". (Many others here seem to agree)
Flavor(s). It is weird many flavors I thought I would like I do not, many flavors I thought I would not like I love.
Juice I use is usually something I will enjoy all day. I have had many that are closer to yuck (Buckley's thought).
If I taste any burn flavor I try to find out why and correct it. Wattage, coil, no Juice (DOH), button being hit when not using, etc.
6.5 watts - 8.0 watts is fine. Really depends on the juice, the tank, how full is the tank (find as it gets empty higher wattage is nice). Dual coil tanks are warmer (not a real bonus now, may have been a bonus earlier on) not much of a "performance gain", if any.
Being able to see wattage, resistance is a necessity to set up my eGo's in a decent range.
Stock coils, I have had some one or two ranges out. e.g. Should be 1.8 ohm and is running 2.4ohm.
Use vaping when you used to chain smoke driving, writing in a forum, reading a forum, watching TV, etc.
I have had real intense cravings pop up at weird times, I have refused many people offers of a cigarette.
Very happy to say the last cigarette I lit made me feel very ill.
