This was one of the things they told me at Mayo too. You can use any hot drink. Just have it first thing in the morning and then eat something with fiber. I use oatmeal. It took awhile to get things going after the trip, but this simple trick plus one serving of Miralax worked for me and has ever since. If I skip the hot drink even tho I've had the Miralax the night before, you can forget it. The hot drink stimulates the vagus nerve http://en.wikipedia.org/wiki/Vagus_nerve and for most people this works.
