I have smoked for over 18 years. I smoked a pack and a half a day. My husband smoked a lot longer than I (he is 15 years my senior.) He was diagnosed with mild COPD. He already was on meds for high cholesterol. We decided to quit smoking together and I did some research online about e-cigs. We decided to quit cold turkey since it worked for us years prior. (Stress and previous divorces returned us to the nasty habit) I ordered us the e-cigs. (Batteries and cartomizers) when they arrived we put the regular cigarettes aside and started using the e-cigs ONLY! I personally think that I could not have done it without these because I was a reflexive smoker and needed something in my hand/mouth in place of the regular cigarette. I eventually stopped using the e-cigs as well. Hubby still uses them because I believe he is more of the nicotine addict than I was. He is still on high cholesterol meds, but at a considerably lower dose as well as we both have lots more energy than before. My daughter has asthma and allergies; however, since we quit tobacco smoking, she is on less allergy meds, rarely has asthma attacks, and more energy also. I am very thankful for the e-cigs and have been a strong advocate for them. I have tried to convert other family members to them. But I do think they are only as helpful as you allow them to be. And I really don’t think their mind was fully set on wanting to quit since they are still using tobacco.
