I am a total spaz about meds when leaving the country. I take everything "just in case". I am even going to take some phenergan (anti-emetic, or anti nausea) that is prescribed to apply to your wrists if sea sick. This stuff is awesome. You just rub it in like perfume, and works within 5 minutes. ( And way cheaper than the $400 for the ship Dr. to give you and injection.) The only problem is that you have to find a pharmaceutical compoundist to make it up. I would just hate to say "I wish I would have brought ____" . Better safe than sorry!
#1 has got to be Gravol (aka Dramamine, Bonine). Can't even get on the plane without it, but strangely enough, have never needed it onboard the ship. The other best thing I packed was a big bottle of Aloe Vera gel, which comes in handy when my sun-deprived body gets too much all in one day! Other than that, it's the essential heart meds, daily vitamins, and a basic first aid kit.
Mike, I understand totally. I think my meds consume half of my carry-on. Then I also need all my hair products, which take up the other half. I also try to bring an antiibiotic, if I can, and prescription pain meds. Thank God, I have never needed them while out of the country, but I feel safer that way. I also bring a list of the generic names of all my meds, since they are not always called the same things in other countries. Once again, thank God, I have never needed that but would rather be safe than sorry.
