Travelling away from home can be an extra-challenge for those of us with health challenges and sensitivities of any kind because it takes us out of our routine. It's not so much the distance but the upheaval that can be difficult to cope with (on top of the extra tiredness that comes with travel) when you probably have well-established survival tactics in place at home that enable you to cope pretty well with your health most of the time. Booking a holiday can feel a bit like planning to blow all that carefully created homeostasis to pieces in the name of having fun and there have been times when I wonder why I do it; is it even worth it (the answer, by the way, is yes). Changes in sleep arrangements and diet can throw health into disarray when maintaining that balance has become a finely tuned thing.
