You're dealing with an Asian Indian man which are a strange breed. (No offense meant to Asian Indian men reading this but it stems from anger towards this particular type)

Good luck..
Only these reason's motivate them to comply :-
- Sincere threat of losing the wife to a better life.
- Money threat i.e money being withheld by the wife from the husband if the wife is the breadwinner.

Attempts to change these type will result in your own ruin and heart burn.
The very fact that he drinks and chews panmasala seems an indicator that you are probably more educated and health conscious than him.

The only thing I've seen that changes this habit is a grave health problem. You cannot change a habit on someone unless that person truly believes it NEEDS to be changed.
You can offer the education and reasons as to why they are bad for him and the family and the effects on family.. But reasoning will mostly not help in alcoholism.
You could try for him to go a specialist dealing with alcohomism but unless he is willing to go it will not help.
If he is willing .. that in itself is half the battle won.
You need to be more specific wrt what stage you are in .. is he willing but don't know how to let those go or is you challenge more of how to make him willing ?

Good luck.
