Hi I am 35 and have salt loosing CAH. I travel frequetly and the last cruise I went on I got seasick (big time vomitting!) because I did not eat. I am not used to eating steak, lobster etc. and the one day I only ate a hamburger because I was not humgry. I DID NOT take extra dexamethasone because I knew the problem was from seasickness. As soon as I was able to get food down, I was fine. Just as a quick note to everyone, the treatment for seasickeness is the same as for morning sickness -- eat frequently and often!
