I'm still taking the pill and I feel dizzy, nauseous, anxiety & tired a lot of the time. This is very uncharacteristic of me. I've been taking it for 2 years now, and I thought I had a brain tumor or something, so I had an MRI, and nothing. Then, I thought I had a heart problem, so I had all sorts of blood work, EKGs, heart x-rays, etc. and I'm in "perfect" health. I kept thinking that it was something after I stopped nursing, and I realized it's because that's when I started taking this new pill. I think I'm going to stop at the end of this month - don't know why I haven't stopped yet!
