Whoa - time for some medical intervention IMO. I agree with Jennifer and Christine completely. One additional option, if Jo does not want to be taking anti-depressants, then encourage her to at least talk to a therapist. Not being able to swallow is NOT the end of the world, although it does indeed feel like it. compulsive and constant rinse and spit is not normal although I had to do it every half hour or choke to death but it sounds like she is doing more often than that.
sorry to hear about this
