I stopped due to health concerns too.
I had suffered from fatigue and lack of energy for a few weeks, which was unusual, as I am a very active person. I decided to see my primary care physician and later learned that my liver enzymes were extremely elevated. I was told how this could lead to permanent liver damage if I continued.
Soon after I stopped, my energy level was back to normal, and six months after that, so were my liver enzymes.
After years of excessive drinking, along with this 'eye-opener' of a health scare, I decided that enough is enough.
