With such people I remind them that it takes a much stronger person to say 'no' than to accept.......thats for the people who go on and on about 'not dinking'. I also say its a lifestyle change......if they keep going on about it I challenge the person to stop drinkng for a month. Chances are they will fail miserably or the person will say that its their 'choice to drink'......If they say that you have them...,say its your 'choice not to drink'.
I think afew people could be feeling that they were that strong they could stop.
