The very first mod I ever wrote - back in 2007!  (The late mesolithic, if I recall.)

I've always thought of potions as small, just a mouthful. The potions in Morrowind are HUGE - several liters in size - bigger than your head!  
 
"Excuse me, Mr. Dagoth Ur, do you mind if we stop fighting and take a short break?  You see, I've got to drink this three-liter Restore Health potion, and since I just finished off six liters of Restore Fatigue potions, I'm kind of full.  By the way, where's the bathroom?"  
 
This mesh replacer contains two sets of meshes that skrink the potion bottles to either 20% or 40% of their original size. Just copy the appropriate meshes into the meshes/m folder.
