SickenedCondition

You feel ill. Sickened always includes a value. You take a status penalty equal to this value on all your checks and DCs. You can't willingly ingest anything-including elixirs and potions-while sickened.

You can spend a single action retching in an attempt to recover, which lets you immediately attempt a Fortitude save against the DC of the effect that made you sickened. On a success, you reduce your sickened value by 1 (or by 2 on a critical success).
