Do you know the medicine for the alcoholics, that does not cause constipation side effect?

Hi guys,
I am looking for an anti-alcoholic medication, that does not cause the costipation side effect.
Right now, I am taking a medication called "Acamprosate" (I may be wrong about the spelling), and it is causing me constipation side effect, so I had to stop taking it.
Do you recommend any other meds that does not give me constipation side effect?
Thanks!
