She has no other symptoms. Past medical history is significant for hypertension. She takes chlorthalidone, an oral contraceptive pill, and a multivitamin every day. Family history is noncontributory. She drinks about 1 bottle of wine every day and started taking a shot or two of whisky or vodka every morning before work to “clear out the cobwebs”. She was recently fired from her job.
