I tried cheese and nuts yesterday which did a good job of masking the aftertaste. Also tried cured Spanish chorizo sausage which helped. I think a big part of nausea is the mental component that is associated with the aftertaste.
As far as tropical fruits go, I found pineapple to be the best. Downside is that it makes my tongue burn for the next 24 hours.
I fed carbonated kava to the list. I have a Sodastream and find carbonated kava to cause less upset stomach.
