Formula?

I’m going to apologize in advance because this post is probably going to be a bit scatter brained/ going back and fourth. My son is 5 months old. I breastfeed him. Since the VERY beginning he has had issues with his belly. Literally the first night he was born he was refluxing because of how fast my milk came in ( I breastfeed my first son). I thought that his gas and spitting up would get better with time. I was trying to keep him away from meds because of thinking this. Well whenever he was 2 months old I couldn’t take it anymore. He was crying and screaming ALL day and night. Like only sleeping for 30 minutes at a time if that. I was exhausted physically and emotionally so at his 2 month appointment the doctor put him on baby Zantac. It seemed like that helped him for a few days but then he was basically back to where he was at. So I decided then to stop eating dairy to see if that would help. It seems like that has helped him but not to the degree that I would have liked it to help him, and now I’m not sure if he just grew out of how gassy he was or if it was the dairy free diet of mine that helped. He is definitely still gassy. Just not screaming all day gassy. He still isn’t really sleeping the best at night. He continuously squirms around and farts and spits up at night and it will sometime take me 3 hours to get him to go back to sleep because his belly is bothering him so I’m thinking about switching to formula. This kills me because I breastfed my first until he was 15 months old. I’m going to talk to his pediatrician but has anyone dealt with this? Is there light at the end of the tunnel or should I switch to formula? If you switched to formula was your baby a completely different baby? I’m worried that switching to formula won’t even make a difference and that it’s just something he needs to grow out of and if that’s the case I’ll be super sad that I stopped breastfeeding. Any advice would be great!!!! I’m at a loss, and I’m back to being physically and emotionally exhausted just trying to figure this out and not getting any sleep on top of it.
