I've always been a binge drinker, but at one time in my life (late 20s and early 30s), I was a full blown alcoholic. Unhappy marriage, bitter divorce etc. I was a 'functional alcoholic and I was able to stop the daily drinking, but I remained a binge drinker.
Due to some awful life experiences in the past couple of years (family death, lost job, split with partner of 10 yrs etc.), I started binging a lot more frequently. I ignored some of the warning signs my body was giving me because too many other things were happening to have time to focus on myself. Until I couldn't ignore it any longer. I sought medical help when my symptoms were too bad to live a normal life.
I've been tested, scanned, ultrasounded and x-rayed to death over the past 8 months. Along with masses of hard to tolerate medication. What it all came down to was that my liver was on the verge of turning cirrhotic. And once that happens, there's no going back.
I stopped drinking immediately. Haven't had a drink since March. My specialist told me that everything I've done to myself is reversible because it's been caught 'just in time'. I just need to follow "The Rules" around healthy living. But he gave me a very clear warning: if I continue as I have been, I will either need a liver transplant or have liver cancer within five years. And you don't come back from that (his words).
Aside from my drinking, my lifestyle was pretty good - diet is fine, moderate exercise etc. And I was by no means a daily drinker. I could go months without it, but when I drank, I had no 'stop button'. I can drink everyone I know under the table. And that was the problem.
I'm only 53. What I've gone through this year with my health, I wouldn't wish on anyone. Please, tell your partner that his drinking WILL come back and bite him at some point. He won't know to what degree until it happens. He could be lucky like me and have the opportunity to correct it and have a second chance at life. Or, he could get a liver cancer diagnosis and only 10% survive that long term. 4% service less than 5 years.
I've learned that what we do to our bodies when we're younger will always have consequences when we're older. Best of luck to you and your partner, OP.
