"I didn't notice any side effects with Errin until I was on it for about 5 months. That's when I realized I was depressed. Cried at the drop of a hat and for no reason, got upset/angry at things that I normally wouldn't think twice about, etc. I didn't know what was causing this but decided to go off the pill to see if that would help. Within a couple weeks, I was back to my old self. I also didn't realize it at the time, but Errin seriously lowered my sex drive."
