Praying for success. My parents both smoked and Dad only quit when he had to have a heart valve replacement and was in ICU longer than normal because his lungs didn't respond. Mom quit when Dad did. Thank goodness. Dad is no longer with us as his pig valve lived its life of 10 yrs. and he opted for no more. Mom is 92 1/2. I never did take up the habit or use alcohol. My addiction was sugar & diet soda, but on chemo it no longer calls my name. Hope that side effect never changes.
