Actually treefern, i kind of tested these ideas already so its probably fine. Here are my test results on the solutions i gav out:

1. This could be dangerous if ur vills are weak or sick. So i therefore recommend using it on strong vills only. (lvl > dangerous)

2. This is definately okay. This was what i did a long time ago when i had a drought. (lvl > safe)

3. This could be dangerous too although not as dangerous as the 1st solution. Therefore i declare this only be used on mentally and physically strong individuals. (lvl > only be used if u are realy very very very very very desperate/impatient)

4. For this, treefern, i hav tried this very carefully. It is very safe to use this solution but u need to be patient. The theory that letting vills being doctors can benefit them is true. I let them learn for a few hours and evry1 is bac to normal. (lvl > safe)
