Ingredient by ingredient
Advil PM (Diphenhydramine) + N-bombCaution
Beyond an ordinary 25–50 mg dose of diphenhydramine, NBOMes make its delirium worse and add heart strain. Keep diphenhydramine to that dose.
At 25-50mg, DPH may assist with side effects of the NBOMe drugs such as nausea and anxiety. At higher dosages, the combination of a deliriant (DPH) and NBOMe drugs is cautioned against. NBOMes are likely to increase the deliriant and negative effects of DPH, in addition to increasing the risk of severe injury and mental trauma. NBOMes and DPH at recreational dosages have additional cardiac concerns such as vasoconstriction, tachycardia, hypertension, which in combination may be exacerbated.

Advil PM (Ibuprofen) + N-bombLow 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.
