I'm going to UK in the Spring. They say traveling from West to East really disruptive to bipolars. Some people have suggested to accumulate your body to the new time zone by getting your sleep patterns in sync.
I'm just going to take two weeks off to travel. Take three days off, take the week trip and take four days to rest when I come back. I think that would work.
Depends how far you are going. I know when I traveled to Spain (my last plane trip before I acquired my physical disability) I had to adjust my medication schedule to a different time zone so my psychiatrist explained to me what was the best way. Even going from the east coast to the west coast of the United States or vice versa will change sleeping schedule and the time to take medications so generally psychiatrists can explain what is the best way to adjust to this specific change over.
