I am 62, have been on one or another anti depressant for 20 years,was on prozac for about last 3 years It seemed not to be doing the job,therapist started me on wellbutrin, the generic Bupropion,sex life was better,BUT I would rather have hair on my head than having orgasm. been taking 200 mg about 2 weeks,hands full of hair after washing my hair.I have noticed SOME memory problems,thought it was my age,ALWAYS have had a good memory, going off slowly,100 mg a day for 7 days then nothing,I also take anxiety meds,going to see if that may be all I need .If not back to the prozac
