I don't know if I'll ever know if my alcohol use caused this. The docs and nurses said no, but I'm very small and older, so I think maybe it did. Nobody in my family has afib so I know it's not genetic. I have been under a LOT of stress in my life thanks to picking the wrong men and the jobs I had, but I haven't been under significant stress for a few years. The thing is that I know several people who drink more wine than I did and they do fine--no problems, so unless my size is a factor, maybe I just drew a bad card and wound up with afib. It really sucks though that there is no going back and that I'll probably be on blood thinners the rest of my life. In two weeks I found out I have two irreversible potentially fatal medical conditions when all these years I thought I was so healthy. I have eaten a Mediterranean diet for almost all my life, did a lot of physical work, walked a lot, hiked, biked, was in shape for decades (not so much now though), so it doesn't make any sense. With the osteoporosis at least I know the culprit--not enough vitamin D, and that makes sense. But with this afib, nothing makes any sense. But, at least we're alive, right? We have something to be thankful for. I know a guy who almost bought the farm with a stroke. He lost his vision, hollered to his GF, and that's all he remembered for five days. It took him over a year to recover enough to function OK and I still don't think he can drive because his vision was compromised, but he's alive.
