I have been on Prozac20 mg for almost 9yrs, Wellbutrin 300 mg bid for about 5 yrs , and Aderrall 30mg SR for 2 yrs. For the last 4yrs i have experienced significant memory loss, word finding difficult, decreased concentration, night sweats and still feel depressed. The Aderall no longer works. I think the Prozac is causing the memory problems and brain fog. My providers says it's not the Prozac. I'm thinking of weaning myself off the prozac first and then the Adderall.
