Yes, I realise that (now, more than ever) but I guess it could have been my undiagnosed diabetes, my period of uncontrolled high blood pressure, or my weight. Or a combination of those.
I gave up smoking a good few years ago with help of Allen Carr's EasyWay, and it was really easy and enjoyable. I've been listening to the audiobook again, but this time it's more pressing.
Thanks for the message. To be honest I'm still trying to process it. It's been a huge shock, and something I wasn't expecting. I expect my thoughts will settle down a bit during this week, and I'll be able to deal with it better.
