i take arthrotec, which contains diclafenac but also either contains, or is coated in something which makes it less likely to upset your stomach. i always take these sorts of tablets with something really stodgy, like bread, or half way through a meal, and find this helps a bit. i do still have some stomach issues with them though. it's a trade-off isn't it? no pain but bad stomach! another thing i use from time to time (although they make me too woozy to take all the time, and constipated) is co-codamol.
