I was hospitalized when I was diagnosed bipolar II (a change after 50+ yrs being considered clinically depressed). I was put on Lamictal then, an addition to the Cymbalta I was taking but without any noticeable effect.
When I went home a month later, I felt better than I could remember ever feeling--I felt as if I were fully alive and able to cope with living ... able to enjoy life.
A few years ago I slid into a deeper depression. My pdoc ended up increasing the Cymbalta by half. He raised the Lamictal proportionally by side effects caused me to switch to Topamax. I began hearing people calling my name, though; the higher of anti-depressant caused anxiety, so I started taking a low dose of Ativan & the hallucinations went away.
Have you checked with your pdoc?
