De-addiction centers in & around Kochi

I am desperately looking for a de-addiction center to admit my father who is a chronic alcoholic since the time can remember him (More than 30 years). This issue has been severely affecting the mental well being of my mother who is staying alone with him, since I visit only during the weekends because of my work. Also, this has casued a lot of financial troubles & shame in the society for our family. Only external help can cure him. Would be really grateful if anyone could suggest good de-addiction centers in Kottayam, Kochi. I have shortlisted the following. If anyone with prior experience with these centers could give me some inputs, then it would really help me in deciding one. 1. TRADA Kottayam 2. Revive Thodupuzha 3. Santhula Koothatukulam
