I started with those (might as well be disposable- they were complete junk) SmokeTip cigs a few years back. Then I upgraded to a DSE801, then an eGo-T this year, then I got a Kanger CEX clearo for the eGo battery... I managed to make a new coil for the CEX (I know, right?) and I went absolutely bonkers this week finally. I got an Oddy clone at a local shop yesterday, and then I ordered an Innokin SVD, along with 100ft of Kanthal A1 and 100ft of nickel wire.. got a set of picks, some fine needle nose pliers, 4 batts.. the list goes on.
Anyway, the SmokeTip was harsh for me at first also, and only mildly settled my cravings for tobacco. All of my friends who I turned to the "dark side" of vaping reported burning in the throat also at first. You'll get used to it. The thing that will definitely be the deciding factor of if you switch or not is a mental factor, and that's pretty much it alone. You have to WANT to get into vaping instead of smoking. You have to KNOW and TRUST yourself that you can un-do your smoking habit and transform it into a vaping habit.
As for that, plan an exit strategy as well. For example, I only ever smoked non-filtered cigs and cigars.. BIG cigars, 2 a day and full inhalation. That said, I started on 28mg nictone liquid. Since then I've worked my way down to 18, and hopefully by the end of next year I'll be on 0 nic and kicking the only habit left over- the habit of actually using the device.
As of now, my lungs are healthier, I am healthier, my breath doesn't stink all the time, I can get my fix at work (I'm a school teacher) without anyone knowing, I am sick FAR less often, and I can actually exercise now! These are some of the main things you can look forward to doing when you switch over.
Good luck, sir!
