Hello poppins1944,
I cut down from over 40 roll ups per day to zero with the mini pipe, but I went crazy for about a month because of CO withdrawal (or some other non-nicotine tobacco based chemical).
It depends upon whether you want to quit normal cigs straight away and how much you want to spend as the vaping experience is different from smoking. Buying certain equipment/liquid will minimise the differences but there is still a difference!!
I think that you may need a bigger vapour producer like the 510 to start with. This is also called the Titan, Janty Dura C etc..
In my experience, it gives the kick of a packet cigarette and quite a harsh vapour. Increasing the nicotine strength may help you but you may be still in the stage of your body adjusting to the different experience.
Hope this helps a bit.
