Really sounds like masochism.

For me the Honour mode is an excuse to use all the debatable stuff the game offers which I mostly or entirely avoided to use in my normal playthroughs, like stealth abuse, shove, scrolls (never used one), potions except healing potions, minmaxing attributes, Illithid powers, magical uberitems etc.
One proposal for your suffering, restrict yourself to two or three magical items per character. You should also never cheese fights from meta knowledge, i.e. not avoiding dialogs that lead to dangerous fights by attacking immediately for example.
And, if you take honour literally, make it the rule to never run away. That is for the real heroes. Would have ended my run yesterday when I fought the Gith patrol from the dialog and all Gith went first, so at my turn I had one dead, one dying on the ground, my main with 10% hp and the fourth in Hold Person. I ran away with my main and came back later but is that honourable?
