Opiates reek havoc on our respiratory system in so many ways.
Sneezing, I believe, is a part
of that. A lot
of people suffer with chronic bronchitis, colds, etc. after stopping the pills. It is all apart of it somehow. I am not a doctor so I can't really tell you how it works I only know I have been there, done that so many times.
That being said, I don't think I have sneezed 5,000 times in my entire life???So keep a positive attitude. It goes a long way.
