Surfacing into a lungful of diesel fumes can get anyone heaving over the side, it's happened to me.
Diesel, as @IT. mentioned, doesn't help, especially with bad viz during the dive, lots of current, some surge, while I'm wearing a hood, and some knocking surface or safety stop conditions.
Probably not the OP's issue but I have a friend who would vomit on the boat after diving - turned out to be co2 related so a rethink on breathing technique fixed him.
All of the above was true on this dive - although I am not sure how a hoodie would aggravate anything.
Whenever I wear a hood, I find that I get headaches and tend to get nauseated more easily. I am not sure if it's because of the pressure, or the resistance that it puts upon my jaw and where it places it, or because it affects how much I can turn my head and then I move my eyes more as a result. Maybe the docs on the board can explain why it might be the case?
Something that has worked for me is to take Dramamine before diving
Good luck and I hope you feel better next time!
I use a simple cap type hood with a chin strap I doubt it. Is yours with a neck that ends at the shoulder?
Now I remember I took dramamine during the surface interval. The DM offered it to me. This and anti-histamines make me drowsy and heavy - even the so called non-drowsy formulas ..
Thanks and cheers!
