Omega-3 + Burping :-/

Kelly
Hey everyone! I've been taking Omega-3 fish oil capsules, and I am constantly burping afterwards and consequently tasting it (not the best flavor coming up). I've tried taking Tums at the same time, but it's not helping. 
Anyone know of any remedies to prevent this? Or possibly any other forms of Omega-3 that don't give this reaction?
