Someone suggested "Ear Planes" to avoid altitude sickness. You can buy at any Walgreens or Walmart and you place them in your ears. Also used for motion sickness when traveling on air planes. I prefer something like this if it truly works vs medications. We're coming up to RMNP in June 2013 and live in Houston, TX area. So there will be a BIG change for us altitude wise. Would like to get different views on what to do to help prevent. I also know hydrating well days before helps too. Any suggestions will be welcomed! THANKS!
