I guess giving yourself a breaking physically and mentally is important. Time out without pressure to 'just sort it out' kinda thing. For me the important things in keeping well are keeping check on my diet and making sure I don't overdo the sugar and caffiene which cause highs and lows in energy and seem to affect my body. Also taking showers/baths help get me going. Doing some light stretches in the mornings and evenings can also be really beneficial for the tight achy feeling I get. Other ideas are heat packs, gel anti inflammatories (ones that go on the skin rather than swallowed, because those tend to irritate my stomach), meditation/relaxation cd's. Talking about emotional issues can also help, since there is such links between emotional health and pain levels for a lot of people. Pre planning journeys, work schedules, incorperating rest time etc is also important to me.

Hope some of htat helps, I'm sure there are so many other things too.
