Hi and welcome wxfdswxc2
I don't think volume matters as much as how you feel - if you feel it's a problem, then it's a problem
as to how can you stop yourself...sites like this help. There's always support here. 'Playing the tape through' can help too - force yourself to remember all the negative aspects of your drinking...play the drinking tape right to the end, and remind yourself that you want change or you wouldn't have signed up here
the best way to make change is to make changes
do you usually drink at home alone or out on the town with others?
