I've been on HRT (Evorel Sequi) for 4 months. For the first 3 months I felt gradually better, ie headaches disappeared; anxiety, grumpiness and apathy largely gone; sleeping better; but for the last month I've slipped back into these symptoms. I don't know if my own hormone levels are slipping away underneath the HRT and have dropped to a point where the HRT is no longer topping me up enough. Does anyone with more experience of all this know what happens to our own failing, erratic cycle and hormones when we use HRT? Does the HRT override our cycle or do we end up with 2 out-of-sync cycles (one natural and one HRT) bumping along together, occasionally clashing and occasionally supporting each other? After the initial feeling of yippee I'm feeling disappointed that the improvement might have been a flash in the pan...
