Thank you to everyone who took the time to respond. I really appreciate your help. I'll be heading to the doctor's before I go away and will ask about the patch and the bracelet. I was under the impression the patch is no longer available in Canada, or at least in western Canada. I'm in Ontario, so maybe I'll have better luck. I'll be going to AC or Dominica in July/August- I haven't decided yet. Whichever I do now, I'll do the other next February or March. Reading this board has been so much help in giving me an idea what AC is like. Cheers, Iris
