Could phosphatidylserine plus be taken while a patient is using aricett?

Possible conflict: Aricept (donepezil) and phosphatidylserine are different, but work in the same direction. Aricept (donepezil) slows metabolism of acetylcholine, and phosphatidylserine may increase acetylcholine & others. Net result could be more acetylcholine which helps brain neurotransmission, but combining both could expose you to cholinergic side effects: vomiting, diarrhea, dizziness, headache, irreg heartbeat, wheezing, etc.
