Just as a reference point, I'll be turning 61 next month. Had a couple of incidences of passing chest pain last year, but it ultimately turned out to be esophageal spasms, that have since vanished. Regardless, my MD did a cardiac cath at the time that was whistle clean (I'm one lucky duck! - my wife talked me into vegetarian ways shortly after I started vaping- that may have helped.). I haven't had any incidences of arrhythmia (yet).
Smoked (ICK!) for almost 36 years. Took up vaping 5 years ago. X-rays are clean, I can still run 7 miles for my workout. O2 saturation on a pulseoximeter is always 98-100%.
I'm still vaping 18 mg nic, down from 36 at the start of my vaping. I'm experimenting with 11mg now, and I think I'll switch to that soon. The wife's at 6 mg, and even that doesn't seem bad to me.
I was interested in your mentioning about the mental "sharpness" and light fatigue when dropping to zero. It'll be interesting to see how this works as that is our ultimate goal. I'm not in a hurry to get to zero as things are working out well with a slow, slow decline in nic levels. I believe in that old proverb.... "the slower you go, the farther you get"
I wanted to pass my experience to you as we are pretty close in age (well, we grew up watching the same cartoons... so what the heck) and it's helpful, I think, to get some medical feedback from your peers in age.
Congrats on saving your own life! As we chat about this stuff, others will get 'saved' too.
