And the best of luck to any considering quitting!
Apparently I don't snore so much now (says the wife) and it's certainly a relief to breath easily and not cough up "stuff" every morning!
I felt a hell of a lot better after just one month (YMMV ofc!) and now I'm ready to enjoy the summer...
One down-side though, I can now smell and taste things, not actually a great thing in London
A small price to pay for better health!
