Hey Wolf,
I never suspected any internal damage, in fact the day of my triple-bypass, I had worked all day building an awning for a bar where I drank often. After work, I had a couple beers there, ate a steak and went home. Around ten pm, an elephant sat on my chest, at least that's how it felt. I couldn't get it off, I tossed, turned, this way, that way, but the damn elephant wouldn't stop sitting on me. I passed out, and woke up eight days later in intensive care. That's when they told me I had died twice, blah, blah blah, and the doc told me I could never drink again. Boy, did I show him, which ultimately led me here asking for help. It could happen again anytime for me, it's always a crapshoot and a risk of not waking up the next day. You don't have to go that far.
