That's right. There is nothing that will magically "cure" a peep of weakness. Time is the great healer. It will take several hours, but so long as a doctor's diagnosis finds no underlying sickness, the peep will get stronger over time.

I had two of them very weak after I cured an illness, The following day they were a lot more healthy and eleted

maybe we can have herbs like in VV3 to cure illnesses!
