I guess drinking is as immoral as robbing an elderly person or stealing from a supermarket if once you drink you get abusive, black out, etc.
I personally have struggled to view drinking as something so outrageous as I had it under control to a degree. However, drinking never made me a better person and heavily interfered with my other interests and goals in life, therefore I made a Big Plan based on sound judgement.
I really enjoyed the Jack Trimpey interview, particularly him asking the caller that elusive question, 'What is your plan for the future use of alcohol/drugs?'
