You might go to the above mentioned forum as there is not one even for heart related problems. It is such a short time until your appt I can only urge you to eat high fiber and drink lots of water. I hesitate to even say that little as we are not medical proffesionals here. I say this only because I lost someone to undetected Aortic aneurism as he was straining with constipation. Good Luck, Ken in Texas.
