I'll offer my insights on bcp in general.
I used them for twelve years I think and I didn't realize until after I stopped (in order to get pregnant) just how disconnected I was from myself and the whole cyclic thing. I was on one particular brand (don't recall it) and my doctor switched me to one with a lower dose of hormone because of pms complications (raging pig beast from hell syndrome). After the switch my moods were just fine. But I was had that sense of being "disconnected", and yeah foggy headache and nausea if I didn't eat regularly.
I believe Yaz is the very lowest dosage you can get and I think it's estrogen only?
