This is going to sound weird but the one time I had them, eating olives and sipping on the juice from the jar helped. I think they happen because your digestion is slowed way down, and the additional acidity helps break stuff down. Not to mention masks the taste/smell.... But the biggest help was backing down the dose. I jumped from 5mg to 7.5mg and bam, sulfur burps. The next week I backed down to 5.5mg and haven't had issues since. Now I go up in 0.5mg increments.
