IBS CRAMPING!? HELP?!

I just got diagnosed with IBS last summer and I've been learning about it with my own body since then. Usually I don't have any triggers besides stress but lately eating a salad or green leafy veggies always gives me PAINFUL UNBEARABLE cramps. I don't know what to do as o have been taking my Dicyclomine but the cramps hurt so bad to the point where I have puked. Does anyone have insight to help me get over this flare-up
