Ingredient by ingredient
Advil PM (Diphenhydramine) + MushroomsCaution
Beyond an ordinary 25–50 mg dose of diphenhydramine, mushrooms make its delirium worse and injury more likely. Keep diphenhydramine to that dose.
At 25-50mg, DPH may assist with side effects of the psilocybin such as nausea and anxiety. At higher dosages, the combination of a deliriant (DPH) and psilocybin is cautioned against. Psilocybin is likely to increase the deliriant and negative effects of DPH, in addition to increasing the risk of severe injury and mental trauma.

Advil PM (Ibuprofen) + MushroomsLow risk, no synergy
Neither substance is expected to meaningfully change the other. Both still carry their own individual risks.
No specific interaction is documented. Ibuprofen's standing risks — stomach bleeding and reduced kidney blood flow — apply in any combination, and matter most when dehydrated, not eating, or dosing repeatedly over a long session.
