I don't know you, however, I'm sure proud of you!!
Cutting out the booze and, too, the Diet Coke is outstanding. Many don't realize the damage that too much caffeine can do to one's heart. It is in so much of what we drink. One of my NYC friends landed in ICU/CCU for days and she spent 7 hours in the cath lab having ablation performed on all of the damaged areas of her heart. It was life changing, to say the least! She's in far better health today.
Amen and hallelujah, indeed!! You sound on top of all of these decisions.
