only use item if stunned

[PhaZor]

I would like a macro or addon button that when clicked will use a Living Action Potion only if I am stunned or movement impaired. I think you can do conditionals in macros like using one spell if in combat, a different one if not in combat, so I figure this logic may be possible for being stunned. I want to be able to spam a button but only have it use the Living Action Potion if it is immediately beneficial. I'm open to using an addon to do the same thing.
