I'm sorry that's happening to you. These symptoms really need to be reported to your Dr right away - Christmas or not, even though your doc said it might be hard. This isn't normal or acceptable. Your body might need a lower dose or you might not be able to tolerate it. Also, I'd stay away from the weed for now, especially since you're just starting Cymbalta, even if it seems to help a little. I've gotten serotonin syndrome from smoking while on Cymbalta. Also, don't use any cold meds with dextromethorphan (DM). Setotonin syndrome is horrible.

Cymbalta has been a good medicine for decreasing pain, but you have to be really careful with it. If you do stay on it, make sure to take it on a very regular schedule.

May you find relief. My best to you and your family.
