depression
"I've been on many SSRI's years earlier and didn't want the weight gain again so I got on Cymbalta. I was very dizzy, sick to my stomach and really really tired. I spent almost 3 weeks in bed. I suffer from low cortisol which causes fatigue and after reading about Cymbalta it lowers your cortisol levels by 40%, so I'm back on Paxil which raises your Cortisol levels."
