I'm not sure that 30 mg is enough to work very well. You might do better at 60 mg. Or switching to Pristiq might be a good option.

I have taken Cymbalta for several years for depression and fibromyalgia pain. Last year it seemed to stop working for depression and I started having delayed-onset sleep (falling asleep around 3 am or later most nights) and needing to sleep 10-12 hours every day.

My pdoc added 7.5 mg Remeron/mirtazipine at bedtime to help my sleep and I have started sleeping well again and my mood is much better. I've been taking the mirtazipine for about two months now, so I feel like it's too early to say for sure that it's going to keep working this way, but I am hopeful.

I wouldn't blame you if you wanted to stop the Cymbalta with the side effects you are having. If you do, remember to taper down.
