Was diagnosed in 1981 with Raynauds.
The Dr.believed it was brought on by smoking.
I was a 2+ pack a day smoker.
He suggested I stop.I did,that day.
It took 2 years for the symptoms/affects to clear up.
It's been 30 years but I still get colder,faster.
But nowhere as bad as it used too.
Good luck to all who read this.
