Is there a way to detect when Restore Health potions are used when they work instantly because they have no duration - without attaching a script to the potions, of course?

GetTotalActiveEffectMagnitude FOHE and GetTotalActiveEffectMagnitude REHE return 0 because the potions work instantly.

(As an aside, I found that any access to FOHE and REHE (and possibly any other MagicEffect codes) in Nehrim.esm, silently halts the script.)

You can use the OnDrinkPotion event handler for that.

Hey MatH, Thanks! That should also get me around the problem of the script failing with no crashes when in Nehrim!
