Overactive let-down

Happy Saturday! Being a first time mom, who is breastfeeding, I have learned that it's all about "figuring it out". My son has been breastfeeding well (or so I thought) but had been gassy and fussy. I did a bit of research and realized that I seem to have an over-active let-down. I have read about this and saw some solutions, but am wondering if any other mommies have dealt with this?
