The tough thing would be if you remember your past life. It would be weird to have a guy f*** the shit out of me and me be a woman. That would be completely fucked up. And many other sexual things that come to mind that I really wonder how these girls did :P
Having two children makes it really unbelievable hard to choose. The will to live vs the confusion/probability to lose the kids. This sucks. But apart from kids I would take the pill at once. I really like life.
