Hi, I've been using Verpamil 480 mg with no Cluster Headaches. I recently reduced it 360 mg with about 2 headaches a week. I have bad side effect of constipation when I take Verapamil (480 or 360 mg). I wanted to find out if any of you guys in the group has the same issue and what you guys do to overcome the side effect of Verapamil. Thanks in Advance..
