Or, another idea, just make them less effective every time you drink one. The first, 100% effectiveness. The next, 75% and so on. Honestly, I'd like to see a system similar to this for all methods of healing so they aren't so overbearing. It would also just kind of make sense, at least I think. You can only heal a wound so many times before it just stops mending the right way and all that.
