ANSWER:

Who cares? Your prayer of 40 days won’t be accepted! Instead of asking when it would start, repent, express remorse and ask Allah for forgiveness. 

If a person drinks alcohol,his prayer is not accepted for 40 days.That means his prayer is valid but not rewarded.Does that 40 days start from his day of drinking or does it start from when he starts to pray.Ex:If I’m drinking today,and I start to pray 5 days later,then will my period of 40 days start from the 5th day or from my 1st day of drinking itself.At which day my prayer will be rewarded?
