For me it was a similar story - started on 11mg cartomizers, got afterward 8mg and this is where I failed and went back to analogues for almost a month - 4 days ago my 18mg juice came with my M401 and today is my 4th day of 0 analogues - only vaping.
Only the first day was a bit difficult, but now its getting easier.
Managed to convince myself these are just a better brand of cigarettes - different flavor, no bad smell, no bad effects - what else can you wish from a cigarette!?!
Well, as with anything - you gain some and loose some, so maybe I am missing a few things from the analogues, but I am sure the positive gains cover it...
And almost forgot - to me its either 0 analogues or all of them - no middle ground, that's what had me started the previous times after quitting completely for months - ...just one cig and then I will stop...
