No advice here. I am in the same boat as you except the gas is painful for my 2 month old boy. I breastfeed and supplement very little. The formulas I've tried when I supplemented were Similac Soy for fussy babies and Enfamil Lipil. Both made the gas and constipation worse. The doctor gave me Enfamil Gentlease but I haven't tried it yet. Tell me if you find a solution please! It makes me so sad to see him so unhappy and uncomfortable because once it's gone he is such a happy baby. Good luck!
