Hi Inspiretoday,
Sorry you are feeling crummy. Hard to know if it is addition or subtraction of meds. Cymbalta withdrawal may take longer than the time to get it out of your system. Just because the drug is out doesn't mean your chemistry has re-balanced itself.
On nortriptyline, I take it and had to decrease from the 25mg I started on originally because of severe dizziness which I complained of affecting my driving. That is the only med I take. I am sure I would have more side effects at my lower dose if I took other meds as well.
Thankfully it is the weekend! Sometimes side effects such as you're having improve over the first few days. Can you kick back for the next couple days and see how you do? If you dont have improvement definitely call your doctor. Gotta stay safe...
Hope you feel better soon. I am sending hugs,
