I was not feeling very good before but not to the point that I felt like calling the dive (my wife had left one window open and I fought the mosquitoes all night).I was trained for this using an agent that caused one to vomit so we would know the feeling and what to do. Feeding the fish underwater can be fun even when you have no choice about it. Of course you can vomit through your reg and knowing that you will have that urge to puke without control you learn that maybe holding that reg in is a good thing. Uncontrolled vomiting is uncomfortable but you can deal with it It will happen one a dive and the experience will be good for you. Whatever caused you both to be ill needs to be checked out. Bad food? People react differently and if you had food poisoning from bad food could be sick for a couple of days. If you suspect bad air then perhaps you recover in several hours.
Were you feeling sick before the dive? If so then perhaps not bad air from tanks. If you were well before the dive then perhaps bad air. You should bring that up with the dive operation as they may want to check their equipment could be bad filters. Did you notice if the air from the tank tasted or smelled strange before the dive?
My problem with throwing out which does not happen often (a couple of times a year) is that the first two spasms almost knock me down. Just like something was tearing my lungs.
