I smoked for 33 years without ever trying to quit. I picked up an e-cig on a Wednesday at a convenience store. The following Saturday I smoked my last 3 tobacco cigarettes and haven’t smoked since (about 5 weeks). I plan on decreasing the nicotine levels of the vapor devices that I am using in the near future. My lungs are clearer already. I find myself jogging to places instead of walking. I am not as out of breath as I used to be. I feel more rested. On the down side, I went through some very uncomfortable withdrawals. I still have what feels like the last stages of a cold. I have had some pretty severe anxiety attacks, but all of this is fading and I look forward to the day I have no more symptoms of withdrawal and I can smell things and taste things and basically enjoy my life!
