Hi, I am 42 and feel I started Perimenopause at around 38 or 39. I started feeling confused,memory lose, muscle aches, dry hair(normally oily and it was coming out.) I had my periods that started lasting ten days or so and I had heart palpitations, felt tired all the time. Just to name a few things. I have been on HRT for awhile and it has really helped me. I thought about going on something else but I needed something soon.Hope this helps you. Polly aka snowdove
