Hello Bax,
I've been on Enbrel for the past 4 years and I'm now trying to wean myself off it.
Same as you, for the couple years previous to starting it I didn't really have flares, more like consistent pain & fatigue that gradually got worse over time. Now that the inflammation/pain are down to a low level, it's much easier to notice when one part of your body starts playing up.
I didn't think I had any stomach symptoms either, however going on the No Starch Diet made a huge difference, so I'm a firm believer in the gut connection even without "apparent" bowel problems.
As for the odd things happening since you started that drug, what sort of things are you reffering to ?
Be sure to report them to your rheumy, the side-effects to Enbrel can be very serious, you don't want anything to get missed !
Merry Christmas !!
