I started abusing painkillers and developed a massive caffeine addiction after switching antidepressants from an SSRI (selective serotonin reuptake inhibitor) to an SNRI (serotonin/norepineprhine reuptake inhibit). The specific SNRI was Cymbalta (duloxatine). My pdoc told me that the effect of an SNRI on norepinephrine can potentiate addictive tendencies. I liked the effects of Cymbalta on my depression and fibromyalgia, so I stayed on it. But now, two years later, I'm coming to my senses and realizing I have to get the hell off this medication.

Anyone have some similar experience?
