I have the weirdest reaction to anything with codeine.  I look like I've been painted red.  Seriously, although it does away with pain, I have an immediate allergic reaction that has me itching from head to toe and my skin changes to a freshly sunburnt look.  Then again, I am also freakishly allergic to caffeine so Anadin is out as well.  With that, I get the weirdest migraine (all sparkly-lighted aura but no subsequent headache!  Steer-range or what?) it's possible to imagine.  Neurofen gives me vertigo and out-of-body balance issues.  On balance, I'd rather have the pain than the after-effects of the pain-killer so I never take any.  Anyone who weakens to that extent and eats pain-killers like they're big girl's blouses, is a big girl's blouse.
