I had been drinking heavily every night for about 8 years. The quantity kept creeping up until 12 drinks a night was as normal to me as eating dinner.
I was hungover to the gills 365 days a year and I just couldn't take one more hangover.
Alcohol stopped working. I started feeling terrible when I drank.
I was diagnosed with a serious but hopefully reversible health condition.
I had to stop drinking or die.
But to be completely honest it was the hangovers that actually made me stop.
I'm only 32 by the way. I had serious health consequences at a relatively young age.
