Gripe water or gas drops

My baby always cries & is inconsolable at night, it starts at 5 & doesn’t stop until 10/11. I mean, he will calm down but then will start back up for a good while. He scream cries. It’s so hard to get him to calm down. I’m debating to try gripe water or gas drops or would u just think it’s witching hour? He’s 5 weeks. He does spit up a lot too, like right after his feeding & sometimes in between when I’m trying to burp him (formula fed) like it’s not just a little spit up either it is like a lot, looks like an oz coming up.
