Welcome, Isabelles!
Most of us have found that drinking heavily is not good for our health or for our enjoyment of life. Things like cirrhosis of the liver can occur without any symptoms until it is far advanced.
Even more important, living sober is an amazing gift! We don't realize how much drinking has affected our lives until we've been sober for awhile.
I hope you'll join us and work on becoming and staying sober. A good place to start is the July 2015 thread in Newcomers.
