Sorry to hear you are still feeling rough. Have you been given the oestrogen tablet to take along with the Tibolone and is this from GP? Also if you still have a uterus and are taking both I hope your GP will keep an eye on your uterus lining with that extra oestrogen, to monitor for thickening. If you have your uterus - maybe it's time for a different type of HRT - I see you've tried one but that was very low dose (25 mcg). You also need to give it (oestrogen) time to build up if you have had menopausal symptoms for many years and have had no periods for some years too? Dose can be inreased gradually. I can see that the last thing you want is to suffer with migraines all the time - so debilitating.
