I actually quit. Swedish snus used to be my poison of choice for well over a decade. Lots of it, too. Bit over a can a day.
Add the odd Cuban and a few regular stinksticks to the mix, and the odd pipe during warm summer evenings ... yeah. Lots and lots of tobacco.
But, as stated, I quit. Wasn't pretty, snus at the levels I was at ... long story short, I probably did go mad for a few days but that passed. No major hassle since.
Then I was at this homebrew store stocking up on yeast nutrient for my mead brewing, and they had various e-cigs for sale. Bought two ego-t noname batteries with ce4 long wick cleartomizers, some juices and a charger.
It is nothing like my old habit, I like a low level nicotine juice ... but mostly I enjoy the act of smoking (sorry, I just do not take toots of vapor ... I smoke

).
Zero nicotine juice with apple flavor is my favourite, and I'm learning to make smoke rings!
Ah. All this started just a week ago, by the way.
Now, the ego batteries I have kinda suck; I want something regulated. So, a Vmax v4 is on its way here. And I think I'll be ordering a GG Odysseus when the next batch is produced.
Its a start. A beginning of a journey I will certainly enjoy quite a bit.
