Hello guys, today i was searching for a mod that makes potion efects last longer, adds potion toxicity (you can't drink too many potions or you will die) and adds drinking animation when we use a potion just like in The witcher.
then i had found a perfect mod that makes just that except for the drinking animation but it didn't work with the latest patch (1.6) and aparently the mod is dead :/
can some one makes a mod like that please? here is the link to that mod, it's a shame that this is dead, would add soo much to alchemy :/

Animation is doable, Imp's MCN uses it for drinking water/ale/etc.
You're not alone in wanting this sort of thing.
