Have used a ecig mod and tank to successfully give up smoking myself 4 months ago now, after a member here turned me on to them shortly after joining and i could still never thank him enough.
My overall general health and fitness levels are so much higher and i can be active without loss of breathe, were as before 2 mins and i would be struggling to breathe after a small jog, just gives you a all round boost in energy and well being.
Made me realise how much my sense of taste and smell were wrecked and only now is it coming back to a normal level, and that is after some major dental cleaning work, but god is it worth the cost and pain to be able to taste the flavors in weed again
Also it is not all plain sailing even without the nicotine withdrawal as you body still gives you pain and discomfort as it repairs itself, i have had chest pains for a month after quitting and coughing up black specks in my phlegm, mouth ulcers and sores that are from infections that the smoke kept at bay till i quit but at the same time caused them. The latest has been a trip to the docs and some tests after i noticed discomfort in my intestines and a swollen lump (not a pleasant wait for a diagnosis) turned out to be IBS that has been there for a while, but the effects of the cig smoke kept it almost dormant so was never really shown more than the fact i always fart lots.
After 20 years of smoking giving up is one of the most life changing things i have done, and the e cig has really made it easy i would never say they are safe when recommending them, but would say hand on heart is 1000s times safer than tobacco smoke. I started out on 18mg nicotine after a month down to 12mg and now for the past month am comfortable on 6mg.
Try find some good quality handmade juice supplier in your country (there is lots of info through Google) and get some juice that way, rather than mass produced brands you get better quality, flavour and customer service and like grow shops the more you come back, the better the freebies.
Feel free to send us a PM any time you want some info or to chat ecigs and will be more than happy to help.
