Please read up on all the negative effects of duloxetine and Gabapentin. Duloxetine is the genetic name for Cymbalta, an anti depressant. It is not a pain reliever. I have heard that Cymbalta takes away feelings of emotion (I can’t laugh and I can’t cry type of feelings) Research has shown that Gabapentin is linked to Dementia. I took Gabapentin for 6 months with no pain relief but a weight gain of 15 pounds. Gabapentin is known for weight gain as a side effect. Doctors are getting kickbacks from pharmaceutical companies to prescribe these dangerous “off label” meds that do not work for pain relief. Be informed about the meds you are taking.
