He has diabetes. He mentioned at one point it got so bad he was admitted to ER. He also may have anxiety because media was asking why don’t you come back to television and he said he’s happy in movies where there is more room for growth. He use to smoke a lot and he may still smoke. He went through a bad phase when Pakistani actors were not allowed to work in India. I remember he was played bad jokes so he may got offended. Just my observation. With diabetes hormones imbalance issue may come along blood pressure. As you can see he is not happy in the interview. I don’t think he drinks alcohol. I might be wrong.
He drinks for sure..i don't think he is alcoholic the way blinds in those days were making him to be
