I wanted to run this one by all of you folks to see if you can figure out what the problem was.
We finally solved it by chance, thanks to a old time diver.
So I'll tell you if you guys guess it right.
My Wife and I went down to Roatan for a weeks diving. First dive was pretty shallow, nothing over 60 ft. My wife started to get a headache after approx. 25 mins under water, then nausea, and then vomiting.
Second dive after SI,same thing, this time the headache was worse. When we got back to shore the DM thought some O2might help the headache, so she used it, and it helped relieve the headache.
Next day she tried it again, this time on Nitrox, to see if it made any difference. Same as before, she got sick after about 25 Mins. underwater. When she came up she was about in tears from the pain of the headache. We had another boat from the dive operator, take her back to shore, and she used O2 again for relief.
I was getting worried.
We were all breathing the same air, and no one else was having any problems.
None of the dives were unusual, so we didn't think it was the bends.
We considered some medication she was taking, but she had dove before with no problems, and had been cleared by her Doc to dive while using the meds.
I called DAN to see if they could be of assistance and they told me they had never heard of the symptoms she was having, and suggested we see a Doctor.
Luck being on our side, the Doc was only a mile down the road, right next to the hyperbaric chamber.
He did a through work up and found nothing, but suggested we do some stool samples to rule out a parisite. He told her to take a day off and see if it occurs again.
We didn't think it was a parasite or illness, as she always felt better after returning to shore, after each dive.
We also didn't think it was sea sickness as that usually will not cause a headache until after you've yacked your guts up. She maintained the headache came first every time.
So... What was the problem?
 
I would've thought a contaminated tank, but your wife switched to nitrox. I got a headache that way once.

Uncomfortable mouthpiece? Dehydration? How many tries do I get?
 
Might be CO2 from shallow breathing. Headache is migraine like, can cause nausea possibly leading to vomiting.

We watched her on the second dive and she wasn't skip breathing. We thought that might have been it, but it was ruled out.

I forgot to mention that we also considerd exhaust gases from the dive boat, but that was also ruled out after it occured on a different boat, and no one else had any problems
Not pregnant for sure.
Mouth piece? now that would be fa out there.
This one had all of us puzzled.
 
Was it something to do with her vision?
 
Hood, mask or neck of suit too tight? For the first couple of years diving I would get severe headaches quite often. & as Ralph mentioned that can lead to nausea and vomiting. I would often have a bit of trouble breathing on the swim to the anchor line. I thought it was my sinuses until I borrowed a friend's hood. What a difference that made! & such a simple change.

The only other thing I can think of is that some piece of equipment had mold growth. Her mask? Reg?
