---Think about a zapper like a blunt instrument that works to keep down the zoo. Depending on your level of infection you may need to use it for a long time. But each week you allow your own immune system to become stronger
---So now why doesn’t a zapper cure you in just a few days? Well first I believe it can’t penetrate everywhere and it can’t kill everything. The older and more hidden the harder to reach but that is OK because they all have a life span and sooner or later need to poke their heads out, plus die off symptoms of killing everything would be too much anyhow. Even Multiceps/Serialis whose cysts can stay idle for +30 years while affecting your immune system will get irritate by a zapper.
