Baby troubles

I have a 1 month turning 2 on the 23. He been fussy nd fighting his sleep since about 2 weeks after he came out from the hospital. I was told he was colicky nd reflux which I kinda new it. But he been spitting up none stop, choking on his spit nd have so much saliva. I did told his doctor about it nd she gave me reflux medication. A few people and I research to try similac spit up or the Gerber sooth. Now they both have good pros nd a few cons. But not all baby are the same. I wanna try to see if it helps my Bby boy with his spits up. Very overwhelmed nd havent have no good sleep at all neither those him. Any suggestions i would appreciate.
