To add my bit here.
For years people were banging on to me about my drinking and I thought they were all crazy. Telling me I was goona die and it's hurting the family etc I ignored them and continued my drinking in pure ignorant bliss, THEN it really DID start to destroy me ( in my mind, anxiety etc) and I ended up in a place inside my mind that I can only describe as pure torture!
