I have a lot of side effects such as increased anxiety, tremors, nausea and total lethargy and fatigue and general feelings of hopelessness and bouts of uncontrolled weeping. Dr replaced citalopram 20mg because it no longer seemed to be having any effect after 5 yrs. Do i continue with the fluoxetine for a little while longer or do i go back to my GP - tjhese side effects are causing me a lot of distress.
