Odeon, you should generally take the NSAID with food (if you can, or at least a milky drink)
And its worth asking your doc for a prescription for a combination of ranitidine or cimetidine, and a proton pump inhibitor (blocks stomach acid production), as well perhaps as some gaviscon to take alongside the NSAID, especially the PPI, it will greatly reduce GI irritation and risk of a bleed or ulcer.
Some NSAIDs are less friendly to the innards than others, which are you on, how much and what for?
I haven't taken any of my meds today. I only just woke up, after yesterday mysteriously disappeared:P
Time for a shot of gear&cyclizine, to take my morning (or rather yesterday night's) dose of clonidine, and a muscle relaxer for my leg. After I slake my thirst and suck down a few cancer sticks that is.
