The purpose of the study is to examine the impact of hot flushes on sleep, mood, and
well-being. The investigators will cause hot flushes by giving study participants the hormone
medication, leuprolide (Lupron), which is a manufactured (artificial) hormone that makes the
body think that it has reached menopause temporarily. Most women begin to have hot flushes
within 4 weeks after taking leuprolide and resume menses 3 months later. The investigators
will administer questionnaires to evaluate changes in sleep and mood over the course of the
study.
