Duloxetine
"I have struggled with back pain for years sick of taking every pill for pain known to man as well as feeling like I couldn't get out of bed anymore I asked for cymbalta. I couldn't be happier I did, I realized the constant fatigue and well as heaviness was severe depression that lifted after a week (a week of side effect hell I might add). My pain is 80% gone and with two bulged disks and spinal arthritis everywhere I am so glad. After the 1-2 week a fog lifted and I could live again I am very thankful i continued with this med even after reading the horrible reviews and sticking with the side effects which were horrible as well. Within two weeks side effects were gone, three months later I can not be more pleased"
