There is absolutely nothing to forgive, I was trying to suggest that the sound I make is the sound of vomitting without explicitly using the word.

I've not found anything that lessens its severity, once it happens there's little I can do but lie down. In my case lying face down makes me feels better, but I still won't be able to do anything for a while. Not riding vehicles on an empty stomach sometimes reduces the chances of it happening but if it happens it's as bad as always.
