Which symptom is NOT commonly associated with S.L.U.D.G.E.?

S.L.U.D.G.E. is an acronym used in the context of recognizing symptoms associated with cholinergic toxicity, often due to exposure to certain chemicals, such as nerve agents or insecticides. The components of S.L.U.D.G.E. include Salivation, Lacrimation, Urination, Defecation, Gastrointestinal distress (diarrhea), and Emesis (vomiting).

Severe headache is not typically listed as a core symptom of S.L.U.D.G.E. This makes it the correct choice in identifying a symptom that does not fit within the associated signs of cholinergic crisis. On the other hand, diarrhea, lacrimation, and emesis are all symptoms that align well with the S.L.U.D.G.E. mnemonic, highlighting the hyperactive cholinergic system's effects on various bodily functions.
