My last period was when I was 47 . I am now 51, roughly how much longer will the menopause last? I have suffered terrible migrains since the onset!

You are considered through the menopause after not having had any periods for two years. Menopause-like symptoms after all this time may be an indication of adrenal stress rather than hormonal.  In this situation it is very important to do supportive work for the adrenals such as a high strength multivit with extra magnesium (this may also help with the migraines), liquorice tea can be helpful as well. I would also suggest acupuncture, it can be very effective for adrenal stress.

Studies have shown that daily relaxation can reduce symptoms quickly so make 30 min relaxation a day a priority. Check your diet too, avoid caffeine and high salt and sugar foods as these can all trigger the adrenals contributing to symptoms. Low iron and low thyroid can also cause similar symptoms so it is a good idea to ask your doctor to test for these if they haven't done so already.
