Ways to relieve gas for 3 month old

My daughter has been having really bad gas, especially at night time. It’s gotten to the point where she is constantly wiggling around when she goes to sleep & the only thing that is comforting her is nursing.. & she ends up sleeping most of the day because she doesn’t get much rest during the night because of having gas.. I give her gas relieve/gripe water twice a day. Once in the morning & once at night time.. I watch what I eat so I don’t give her gas, I also had to cut all dairy out because she was throwing up constantly.. so I don’t think it’s what is in my diet.. I gave her formula yesterday so she would poop in hopes that it would relieve the gas alittle bit, but I don’t think it helped any.. I’ve put warm wash cloths on her belly, I’ve done the leg exercises to help get rid of the gas, but nothing seems to help.. does anyone have any suggestions?
