I started smoking at a very young age,and continued for nearly 30 year’s and as most of us do in my mind it was never going to bother me, until about 8 year’s ago when I was diagnosed with copd. with the weight of that diagnosis hanging over me,I tried the gum,patches chantix,the chantix had me ready to pull my hair out,even tried cold turkey nothing worked for me. then 2 year’s ago I was searching the web and found electronic cigarettes. and within 2 weeks using that little thing i wasn’t smoking anymore, I started out with a cig look alike at 24 mg it wasnt quite strong enough so i moved up to 30 mg and a stronger device a mod.and that stopped the craving’s, then i slowly lowered the nicotine level a little at a time until it was finally zero. I haven’t smoked since as for my health my lungs will never be back to normal,but i no longer have the cough, and the shortness of breath has become allot more manageable. it’s hard to believe that such a simple solution has taken so long to become available.
