I've recently been prescribed Pristiq (50mg) after trying Citalopram (20mg). On the Citalopram my mood improved slightly – felt kind of numb emotionally, but physically I felt horrible. Headache, anxious, pounding heart, constantly hungry, didn't sleep well, felt as if I had been poisoned, just overall blah. I haven't started taking the Pristiq as I understand it's more difficult to stop and I dread the potential side effects. I was diagnosed with clinical depression in my early twenties and am now in my late fifties. I have tried Paxil, Welbutrin, and Prozac in the past. Over the past six years, my depression has been worse than ever. I'm interested in hearing from folks that have experience taking Pristiq. Thanks in advance.
