Birth Control
"Can&#039;t recommend. The mood swings and fatigue were nothing compared to the violent nausea I experienced when taking this pill. I actually mistook the symptoms for food poisoning for the first couple days I was taking it. I figured my body would adjust eventually, but after a couple weeks I couldn&#039;t handle it anymore. The sickness subsided immediately when I stopped taking this pill. 
Estrogen can irritate the stomach, so it might just be that I&#039;m particularly sensitive. I&#039;m now taking a progesterone-only pill and so far no upset tummy. :)"
