So I accidentally ha Phil eat some rotten meat instead of destroying it...
How long does that last?
Any way one can shove two fingers down his throat and make his throw up, or eat something to neutralize it?
If there was a Pharmacy next to the C-store.
Not sure how it is in the US, but here in Singapore they sell all kinds of semi-surgical stuff (syringes, scalpels, band aids etc.) not to mention medicine.
You can visit the clinic (on the main DMC map) - they sell drugs there, as well as a selection of medical procedures.
