Bonnie has always been able to enjoy good sleep in the past. No matter how stressed she might be, she could count on laying her head on her pillow, falling fast asleep and waking up the next morning refreshed and rejuvenated. However, when she reached her mid 40’s, her periods started changing and she began experiencing sleep problems. First, she would just have insomnia the night before starting her period. As her periods became more irregular, she started waking up in the middle of the night around 2 or 3 am and would find herself wide awake and unable to go back to sleep. With so little sleep, she would be exhausted the next morning. Over-the-counter sleep aids would make her feel sluggish the following day. By the afternoon and early evening, she would be crashing. She came to see me on maximal doses of prescription sleep medicine and still was sleeping poorly.
