Awake at 3 a.m. again? You're far from the only one.

In the SWAN study of 12,603 women aged 40 to 55, 38% had trouble sleeping in the past 2 weeks, and 45.4% in late perimenopause. Worth logging tonight: what time you woke up, night sweats, evening alcohol, caffeine or spice, and how you felt the next day.
