yes
no you should not tell your husbands mom about his health
call him out on it and tell him to stop, or tell your husband to do something.
no way
you should tell you father that you don't like the way he is drinking. But if he does not listen then you should take to your teacher or the police station. It is not like they are going to take you father to jail, they will just talk to your father and tell him to stop drinking, and start training him.
Confront the husband first, then talk to the wife if the husband doesn't stop.
Only the family elders can tell the Goutra of the family. A man or unmarried woman always belongs to the Goutram of the father, once a woman is married she converts to her husbands Goutram.
That should come out in 'discovery' see a lawyer, or 'We the People.'
Yes. Normally you should tell a close friend.
You'll need to tell your husband first.
If Comes home raw
I know there will be people who will tell you to mind your own business, but we're talking about family here, and in my opinion, family is always your business. I think you should tell your sister. Friends will come and go, but family is for life.
Sit someone you trust most down and tell them you've started drinking again, and tell them you need their help.
