Help. Reflux? Lactose intolerant?

My 1 month old has been more fussy lately after he eats.

About 2 hours after he has his formula he starts getting gassy and fussy. We tried giving him gas drops and gripe water but they don't seem like much help.

He gets upset if we set him down weather it be his bouncer or bed.

He gets himself upset enough to where he'll puke.

I'm wondering if he's having tummy issues or if it's just a baby thing?

Neither of us have gotten any sleep lately and it breaks my heart that I can't find a way to calm him down.
