CQ - yes it most definitely depends on which one's right for you. I had other pills that turned me into a raving screaming crying-in-public lunatic woman. This one was just right!

There are all sorts of new ones on the market, your dr should be able to work out, based on your main symptoms, which one is possibly better for you, then it's a case of trying it for a couple of months. If it's not right, go back and change it again!!

BTW I'm not advocating the PILL ahead of other therapies, I just mentioned it because MR's post asked about contraception. You can do wonderful things to help your PMT throught diet, meditation, massage, TCM, acupuncture, herbs, etc. The more in balance you are, the less noticeable the symptoms will be, kwim?
