Hi rich
Im sorry about your health news. My dad had stents placed after a heart problem 15 years ago. He didn't realise he was living with chest pain from occluded arteries until after. It is amazing what can be done.
You are tough. With the things you have triumphed over, you can beat the cigarettes.
I have not been very active on steemit, I just popped across to catch up on your posts. I'm shocked to hear about your troubles. As you know I'm not the praying type, but I know you are, so I'll shoot one off for you to the heavens / stars / ether. Take care. X
