Thanks Jack. I think I meant--does alcohol compound the MLC and make it worse? I used the word "prolong" but the more I thought about it after I posted it, I don't think that was the right word.
I have a sister who was an alcoholic and it took years and a subsequent arrest before she went through treatment. Coming from an Irish-Italian background, alcohol was a big part of my family.
I know they have to hit rock-bottom before things begin to change. I guess I can only pray that rock-bottom isn't him hurting himself or someone else.
