He has heartburn about 3 times a week. So bad that he will just start throwing up all night. I'm sure it was from that pasta. I gave him some tums but he said it's not helping a lot. He still has it. He won't go to the doctor because "he's a man" 🙄🙄🙄 what are some good remedies for a severe heartburn?!
