My hubby takes Librax to help with the cramping - it's a smooth muscle relaxer and it seems to help some. When he's really bad off, he uses a heating pad on his gut as well. Hot baths seems to help too - we're still trying to figure out if we can get a hot tub prescript
ion so insurance will pay for it.
I've also heard peppermint is a natural anti spasmodic - you can get capsules of peppermint oil (better than fish oil burps!) or sip peppermint tea. Every little bit helps!
