Yesterday while I was out of the house my father was working and started eating peanuts. Afterwards, he drank about 10 small beers and I've warned him about drinking. He says he has strong stomach pain and he can't burp. He went to the doctor yesterday but he had to wait 8 hours and prescripted him medicine but he says his pain is even stronger than before.
Any home remedies for this?

How can he treat it?
