I would like to start by saying I have been a pack a day plus smoker for more than 20 years. I started smoking when I was 11 years old and am now almost 35. I have tried several nrt and prescription anti smoking routines including the patch, nicotine gum, chantix, chewing tobacco and disposable/cig alike e-cigs and had returned to cigarettes after all of these within days. Recently I have purchased and APV ego mod style e-cigarette and have been exclusively vaping high strength 24mg e-juice for 21 days(the longest I have ever gone without a cig). I have already noticed an increase in my senses of taste and smell. An increase in physical stamina, decreased shortness of breath, and my wife has commented several time about how much better I smell. I have also noticed an increase in coughing and phlegm production which I attribute to smoking cessation and suspect it to be temporary due eliminating toxins from said cessation. I realize 21 days may not be a success story for some but as stated previously this is the longest I have been without a cig for a long time and have yet to have a craving for a real cigarette (although I still step out with the smokers to vape) I look forward to reading more success stories from others who have had similar progress.
