Formula mix up!! Help!

Stupid me thought the wrong formula. I’ve been feeding it to him for four days without realizing. In those four days he has become very colic. Will not drink more then an ounce at a time. When before he was drinking 3 ounces. He is also now throwing up almost constantly. Could switching the formula have done this and when I correct my mistake. Which I just did now. Should he be OK and how quick!?

He’s suppose to be on similac neosure and my sleep deprived ass got efamily neropro,,,,

I hope to the gods the formula was causing this and he’s not sick or colic :,(

I feel so shitty!!
