Vitamins Heal You
If you have sleep disabled (like in most Multiplayer servers), vitamins are absolutely useless. This mod makes them slightly more useful by making them heal you by a small percentage. This percentage varies depending on how hurt are and other variables are so adjust accordingly in your sandbox settings.
Made and tested on multiplayer (as a server mod)
Should be compatible with everything since it only adds a check when taking the vanilla vitamins. They still remove fatigue.
