TBarry,
You are lucky if you get the perks. I wouldn't want to change that. They are a good pain killer. Stronger than what I take. I take norco and it helps a lot. But perks are even better for pain.
I hope that you get some relief soon. The cymbalta can take up to six to eight weeks to reach their full potential. How long have you been on that? You might have to give it some time.
I just read your other post so I thought that I would add to this one. Give the cymbalta time to work. And the side effects should go away in about a week. I hope that this works out for you.
Take care, and I hope that you are having a good day.
Hugs, Karen
