I have taken welbutrin for nearly 10 years. Have loved it however slowly through the years ringing in my ears has become almost non stop and unbearable. Dr. suggested I try Prozac. Ringing in ears definitely less but now I am fatigued all the time. Wake up tired no energy or desire to do anything. Sort of don't care about anything. Taking 20mg now, called Dr will talk to him tomorrow but considering dropping to 10mg. Any suggestions or ideas from anyone based on your experience. Oh, started antidepressants & hormone replacement after hysterectomy 10 years ago. Thanks for your input.
