wanted to update you all since you were all very helpful. I've been to the doctor (I've now gotten these headaches after sex an after exercise) and with my history of headaches and this sudden change in headache patterns, I am headed for an MRI tomorrow. In the meantime, until they are certain everything is benign, no fun more me--nothing that will raise my heart rate! <_< So, I definitely will not be posting here for the time being. Time to think pure, virtuous thoughts!
