Hi again, About 4 months ago I started on Cymbalta. It was wonderful - I couldn't believe just how much I could do so quickly again - watch TV, read books, do housework, cook food for my family, etc. However, in the past few weeks I have started to feel fatigued again. Went to the doc & he took all the tests - only my thyroid was a bit elevated but then again it usually is. I think the vivid dreams have something to do with it - I dream flat out all night - really complicated, challenging dreams. I think this is depriving me of enough deep sleep each night. This dreaming only started with the Cymbalta & it has just got worse & worse. I have heard that the benefits of anti-depressants can sometimes "wear off" after a few months. I am wondering if this may be what is happening to me with the Cymbalta. Has anyone else experienced this?
