Hey guys stopped taking fluoxetine 3 weeks ago today and still cannot feel much recreational effects on opiates (tramadol, oxycodone and codeine) even at high doses, will this happen all the way until the 5 week period it takes fluoxetine to leave your system or should that problem have been solved by now? Also not sure If this had an impact but started taking lithium at the same time as I stopped the fluoxetine, any help would be much appreciated
