Cam, someone else asked if you have a good rheumatologist. I think that is key to it all - having an expert who you can keep in touch with and monitor progress, even if you are opting to be conservative in your treatment first off.
Like Sue says, it doesn't have to be all or nothing. You won't know how you feel on meds unless you actually try it. It could be that your AS does come as flares with manageable bits in between. I'd say talk with your rheumie about trying a proper course of NSAIDs - not for pain, but for reducing inflammation. Let yourself experience what that is like, then you can make a more informed decision about whether you take them or not. Also talk about what other drug options there are, and what your rheumie thinks about early aggressive treatment vs waiting till things get really bad. To me, things like diet and exercise are essential self help parts of the whole plan, but they aren't enough on their own. Meds aren't enough on their own either.
