Tabby - regarding Tegretol OD - i've been there....
*everyone/anyone* this is going to be gross - re puking, so if you are sensitive, don't read it.
i do not understand why your hubby is still throwing up!!!!!
I OD'd on Tegretol too, by accident, once.......
i puked my eyes out ... could not stand, could barely crawl, quadruple vision... had to call 911.
by the time they got me to ER i was beyond stomach contents i was puking bile.
they gave me an antiemetic to stop the puking and put me on fluid replacement to get the carbamazepine level down.
maybe you could ask the doc what they did/are doing to help him, and whether they have given him an antiemetic... (maybe they already did and it was of limited use.

) if not, maybe they'd be willing to give him one.
poor thing i feel for him, that was a horrible experience.
