Help! Over feeding trouble

I’ve been overfeeding my baby! I never thought it was an issue.. but he’s gaining a lot more than average weight gain, he is ALWAYS sooo gassy and fussy because of it and been spitting up and vomiting quite a bit!! My doctor said he wasn’t allergic last check up I had. I just now realized that I’ve been over feeding him by more than 300ml a day based on his current weight. He is always wanting more and more, waking up nearly every hour of the night crying and won’t stop until he gets a bottle.

How do I fix this?!?

Please help!
