I get it, I really do. So many times I think I know what I need and the opposite is true!
The estrogen in Yaz is stronger than Q, so I guess you're suffering from the drop down? How you describe your head is my low estrogen feeling, but we are all different, don't forget.
I guess you need to ask yourself which symptoms affect you most? Which are the ones you want out of your life? To feel perfect, all the time, is just not achievable with hormones like ours, sadly. I've had to accept that weight gain, lower libido and spotting are slightly more acceptable than the more distressing symptoms I have. Don't like it, but kind of begrudgingly accept it.
If it is your psychological issues which upset you most, then see your doc and maybe consider altering your AD as a priority. If it is the up and down of fluctuations, the unpredictability, then consider suppressing ovulation. I think this is what has helped me most - even though the dose in Q wasn't quite right for me.
That information sheet by Nick Panay for NAPS is really helpful and reviews all the different treatments for ladies with PMS or peri fluctuations.
