hi guys-- can anyone tell me real quick before i drink my vial if i can return to my zapper skin after? or will contracting a virus "overwrite" the zapper skin?

It shows up on top of your zapper skin, it won't remove zapper or zombie skins. There's a warning after you select to drink the vial (which is kind of poor planning since most people wouldn't be expecting two confirmations to drink it, and a warning after you hit okay)
