Reflux management

My baby was diagnosed with Infant Reflux a few days a go.

I just need some help from others going through the same thing.

How long does feed times take?

How much does your baby drink??

My LO would drink 60-90ml and in between the seeding he would gag, cry and scream non stop, then I pick him up to burp him, he almost brings everything up and sallows it back down and starts crying non stop

This is making me feel horrible, he feeds for 10 mins and cries for half an hour, I keep him up right also.

He is on thickened formula at the moment since Wednesday

Please ladies any tips on management would be appreciated
