Hiya, don't know if it gets worse with menopause but I woke up this morning at 7am saw it was still dark and literally couldn't drag myself out of bed. I can't bear the darkness in the mornings.
My daughter, 22, has suffered from SAD since she was a teen. She uses St. John's Wort when it gets overwhelming as otherwise she can't study properly- she's currently in her second year of university.
You can get it from various online sellers, happy to give some suggestions if you like. Do NOT buy it from Holland and Barrett, I worked there and they are a total rip-off!
Hope this helps.
