Aricept as part of an ADD "Cocktail" I have used Aricept since 2002 when I heard a Harvard researcher discuss its effectiveness with ADD. I am an adult female for whom a "thinking" cocktail was necessary to make the work day function effectively. The "cocktail" has been Adderall-XR 30 mgs in the morning with a "booster" dosage about 4-6 hours later (which varies) of Adderall (regular) followed in mid to late afternoon with 10 mgs of Aricept and 150 mgs of Effexor.The only negative side effect I have had with Aricept has been occasional lightheadedness. This comes and goes depending upon the amount of sleep I have had. I found introducing Aricept into my regimen enlarged the "net" of my thinking abilities; allowing quicker and more efficient processing of information. I have NEVER tried Aricept as the only drug I take.
