I want give up my liquor habit and I want to improve my child welfare and education how?

were you on liquor when you wrote this? damn man
well i believe first thing should be your liquor habit, find someone who wants to quit liquor like yourself. go to those kind of meetings(i don't remember the name ) and share with other people who have the same problem

if you can't stop it right away:
keep on drinking but make less and less everyday til you get to none
start drinking something else (alcohol free), and as you make alcohol less, add to the amount of the other drink

after you quit liquor for a while your blood gets clean and your brain goes back to working normal and you can think , grab a paper and write the names of people that you care about in you life, if you couldn't think of any go back to your habit
but if there is only one name then you have a responsibility so try to fulfill that

get RID of any alcoholic drinks at home

STOP going to bars and other alike places

go to a gym or EXERCISE at home. Healthy Body, Healthy Mind

go to WORK, find a sec job to fill your time if needed: you make more money for education of your SON - you get more tired and sleep sooner

and hopefully your WIFE comes back when she sees that you've changed

DON'T get drunk, you get drunk you lose your MIND, you lose your mind you lose your LIFE

and TEACH your son not to lose his life

best wishes
hope YOU make your life good
