Please help ! Looking for an affordable Rehab / Care centre for my 65 year old father

Hi All, I'm in a very stressful situation currently.

My father has been a chronic alcoholic and smoker for most of his life ( 40 yrs ).

He's very very tempered, narcissistic and he blames my mother for every single thing happens.

He's under heavy psychological medicines.

Still , things have been getting out of hand lately and it is becoming unbearable for me and my mother.

So the best thing I can do is to keep him away from us.

I'm looking for an affordable Rehab / Care centers who deal with such kind of patients.

I can't afford expensive ones.

Also I'm not sure what else I can do.

So please help and suggest if you are aware of such centres in and around Pune.
