"chemotherapy brought on bipolar disorder and several years of meds and regular sessions of therapy has made me feel some what normal. i take 300mg of effexor, along with 800 mg of seraquel. my side effects are some memory loss, thirst, and fatigue. i do have an issue with staying engaged. however, my unrealistic fears are not something i think about as often, and my anxieties are minimal. i had some income issues, and i did not take my meds, all my symptoms returned. i suspect that i will need this drug for my entire life."
