Due to multiple meds and anti cholinergic drugs i.e Dicyclomine, Loperamide, bentyl, benydril; I am afraid of High Risk Cognitive Toxicity as I am taking Donepezil for memory and am looking for a replacement for the Donepezil. However I don't want to use SSRI's as the side effect is diarrhea, which is my problem along with severe cramping. Please give advice. Searched many sites and nothing seems to fit. Thank you
