My story is similar to other folks posting above...but it took ME a LOT LONGER to experience 'overnight success'.
In August 2009 I bought my first PV (a cig look-alike) and purchased a supply of the most god-awful 18mg juice you could ever imagine (corpse drippings). Needless to say, I was unable to 'fall off the wagon' because I could not get ON the wagon!
I continued using my small battery PV cig look-alike, trying different juices every once in a while, but was never able to make the switch to vaping.
In September 2011, after 32+ years of about 40 analogs per day (and 2 years of trying to vape 'roadkill'), I upgraded my hardware to an Ego-t (hate the 't'...love the batts), found a new juice vendor, raised the nic level of my juice from 18 to 24mg, and accidentally found the vaping combination that worked for me! With the right combination, I suddenly preferred vaping over smoking...and I
still have my last half a pack of Winstons sitting here on my desk, collecting dust.
I did fine for the 1st six weeks, then 'the craving' began to hit me really hard. Those Winstons were calling my name, but then I heard about WTA (whole tobacco alkaloid) juice. In desperation I placed a RUSH order for WTA juice, hoping it would arrest 'the beast' before I gave in to the analogs again...and IT DID THE JOB!! WTA juice easily got me through the next two months, and I haven't had a craving since. I still use WTA juice about twice per week, but most of the time I vape 'nic only'.
I apologize for the long story, but I wanted you to know that 'success' sometimes takes time. Finding and getting the right combination of hardware and juice sometimes takes time. Yet, from my first puff on a cheap PV, I
knew this could work for me, and 25 months later, it DID!
Don't beat yourself up. Be nice to YOU! You're experimenting and learning, and you know more today than you knew yesterday. Tomorrow you'll even know more than today. Every step is another step toward your eventual success, because one of these days, you'll find the combination that you prefer over analogs. When that happens, you'll be done with analogs, and it will be a pain free transition. I had to work for my 'success', and I finally found it! If it can happen for me, I guarantee it CAN happen for you!
Good Luck!
