I'll give you my straight-out opinion....and you can take it for what it's worth. I'm a recovering alcoholic. I've been sober for over 13 years. I don't say this to brag, just to state the facts.
When I was drinking, I had all sorts of symptoms. Heart arrythmia, pains in the chest, more gastro-intestinal problems than I want to list...and the list went on. I kept drinking anyhow. When I drank, it numbed the symptoms...or at least I got to where I didn't care about them.
I finally got sober at the age of 44. Many of the pains and complaints went away when I stopped drinking for good. Some didn't. I went on to have the 1st of 3 MIs (heart attacks) at the age of 49. Since then I've had 2 more MIs, my gallbladder removed and quadruple bypass surgery. At the moment, I'm considered to be 100 percent disabled due to Coronary Artery Disease (CAD.)
I have no idea how much of my medical issues (if any) were caused by my drinking. But I know that drinking masked the symptoms and caused some of its own. At least today I can pretty much attribute cause and effect with the things going on in my body...I don't have to wonder if it's an extra bad hangover or acute alcohol poisoning (not always fatal...but darned unpleasant.)
One of the things that kills many alcoholics is esophogeal hemmorage. When this happens, a blood vessel in the esophagus bursts and the alcoholic bleeds to death while vomiting up his own blood. Not a pretty picture. But it does happen.
I know that when I was drinking, I didn't want to stop...period. I wanted to be able to continue to drink, hoping that I'd be able to keep it under control, or not caring whether I did or didn't. I only quit when I came near enough to death to see white lights coming toward me. No, I'm not kidding. It was the first of several near-death experiences I've had and when it happened, I got the message that I had to change my ways. Simple as that. I went to AA and haven't had to drink since. It hasn't always been easy...some times have been rough. Not in fighting the craving to drink, but facing life without the aid of alcohol. Quiting drinking isn't hard. Living life on life's terms is.
If I were in your position, Clarky, I'd see if I could go 90 days without a drink. That's about how long it takes for the effects of heavy drinking to completely clear the body. In AA they say, "stop drinking for 90 days. Then, if you're not happy, we'll happily refund your misery." If you could do this, you might just be able to see what symptoms remain and what goes away. It's up to you, of course. I'm just glad that I don't have to drink today.
Best of luck to you.
