I Care For An Elderly Woman With Alzheimer's. Over The

I care for an elderly woman with Alzheimer's. Over the past week she has been vomiting up breakfast every 2-3 days (not consistently). I've changed her breakfast menu and this seems to make no difference. Could it be her medications? She is taking Clopidogrel, Metoprolol, Losartan, Metformin, Donepezil, Atorvastatin, Citalopram, and Memantine. She has a Dr. appointment this week, but her husband is worried and so am I.
