Breast feeding

I have a question, does anyone here bf their infant with reflux? His reflux is getting better, on prevacid for a while now and was diagnosed with mspi but I badly wanted to bf. Everytime I try he gets a lot of gas and goes back to colicky type symptoms and does not sleep well at night. I have tried everything with my diet etc… But feel so discouraged. I hear bf is the best thing you can do fir reflux and really wanted him to enjoy all the health and emotional benefits of bf. Has anyone conqured mspi with breast milk or should I just give up. I ball everytime I try and fail! Any advice?
