The first step is seek and existing add-on which removes animations. If you don't find any, asking politely will probably net you a better response than telling the authors their healing system is 'stupid'.
IDK, something along the lines of "I like your mod, but would prefer not to have the blackout animations when using medical items. Is there an easy way to remove them?"
