Aricept
"63 yr old woman, early onset Alzheimer's diagnosed July 2013. Prescribed Aricept 5 mg and Namenda. Found Namenda made me agitated and angry so quit. 10 mg Aricept and serious side effects. While waiting for new doctor to take over past neurologist's care, have adjusted meds myself to keep the memory help - which is astounding - and lessens side effects which includes severe muscle cramps in legs, water retention, ankle and hand swelling, back pain,  increased blood pressure, heart palpitations. I now take 1/2 of the 5 mg tablet in morning and am still retaining benefits with reduced side effects. Aricept restored my ability to read and gave me energy and focus I have not had in 3 years. Lower dose on most meds always works better for me."
