I will be 63 this year in May. I smoked about 46 years, two packs a day for a long time. When I decided to quit last year, besides the starter kit and juice, I also bought two boxes of Nicorette gum to help get me through some of the tough times and also to use in places where I couldn't vape (like the doctor's office I'm headed to in a couple of hours). I haven't used the gum much at all, but it has been there if I needed it. A couple of months after I quit, I was having a particularly hard day for no apparent reason. I went out and bought some Red Man Golden Blend chewing tobacco. Just a tiny bit between my cheek and gum helped a lot. Have only used that 2-3 times.
I haven't read any posts about this subject, but I noticed right off that sometimes I felt like having a cigarette would help me breathe better. Well, yeah, it definitely would, because cigarettes have bronchodilaters in them, think asthma medication. That helps open up the airways. And the reason behind that is so the smoke can be inhaled easily and more deeply so the user gets more addicted. Vaping doesn't have that. It took me about 10 days to be able to inhale the vapor at all. I had to start with low nicotine and small drags to get used to it. I just couldn't get it into my throat. I was a little discouraged at first, because it didn't seem like smoking, and I figured I was doomed to just vapor in my mouth, no inhale. But I did get the hang of it eventually. Actually, I don't lung inhale anyway, I don't think, not even with cigarettes back then. More like just to the back of my throat and then out.
I've been quit since July 2, 2013, a little over six months now. I can't say it has been hard at all, and really easier than I thought it would be, but yet I've been in the grip of some of those tough times once in a while, especially the first few months. They never last very long, and now I can't remember the last time that happened. I know some here say they stopped smoking when they started vaping with no issues at all. That's great, but it didn't happen exactly that way for me. Besides the cravings, I also had a few brief physical things, like stomach problems and even four zits on my face! I do know one thing--I never did like smelling smoke on people, but now it's REALLY offensive to me, ugh!
Just keep your gear in order and your juice stocked. You'll be okay. There are better days ahead.
