In 2007 I almost took no insulin first two weeks and was continously testing. When I got tired I had to make sure I was tired and not to low because of the insulin intake. The 2010 trip will probably be 90 days so I'll have have supplies shipped ahead a couple of times. Most Endo doctors would suggest not doing the trip at all, but I think partners is the answer to safety. I had 2 in 2007 and when I said I to eat to let food catch up to the insulin they where fine. Thanks for the info from your wife!
