At 54 and 36+ years of smoking I have never been "diagnosed" with COPD but as someone already said, I probably do have it to some degree, so I cannot comment about the condition with any authority or experience but...
Christmas day last week I got a call informing me that my oldest sister of 65 was in the hospital. She has COPD and has been smoking heavily for her whole life. Long story short, they said she was about as close as you can get from either going directly to the emergency room or going to the morgue. She spent 4 days in the hospital and came home with the patch Monday. I spoke with her yesterday and she assured me she has not had any cigarettes at all and mentioned a few good things she's already noticing about her breathing getting better, not as out of breath climbing stairs, etc.
She is very much like myself, someone who really enjoyed smoking although she did it too heavily for too long. She has been kinda following my progress of using a PV over the past 55 days (I quit analogs on day one) and is now showing more interest than ever in trying mine and learning what they are all about. I immediately considered buying her a starter kit (Joye 510) and have it mailed to her house, but I want to see how she does with the patch. In a couple of weeks she'll be visiting us (she lives a distance from us) and if by then she did sneak in an analog or two (or more) then I'll be hooking her up with her own PV.
There's been no clinical studies, no trials, no evidence whatsoever to suggest anything either good or bad about PV's, only what we have all experienced. So it would not be right for me to suggest to her that it would be better for her in any way, except if in fact she cannot stop smoking analogs once again. That's when I'll step in and at least tell her everything I know and give her the alternative of a PV.
So, for anyone here who has been diagnosed with COPD, I know that I would be very interested to know your personal experience using a PV whether it be good or bad. Actually, where else can anyone go to learn about first-hand experience with PV's than right here on these forums.
Keep us updated on your experiences!
