All I can say Redlocks is my experience and then you can take from it what you may. I started on gel and utrogestand in September 2018. I have a mega history of hormonal issues going back to a teenager which I didn't know about until I got to this meno lark when all of a sudden lots became clear - no consolation - but at least I have some answers to questions I have been asking for nearly my whole life! With my hormonal issues I had a mega history of depression and took AD's pretty much the whole time from age 15 until 51 when I ditched them!
My body doesn't do progesterone very well and it made me flat and depressed when I started and has done so to varying degrees since I started 15 months ago. Anyway having read here and learnt a lot, although I should take utro continuously I only take it on a cycle and I had to start slowly. I could only manage 200mg for 7/8 days for the first 4 months. After that it went up to 9/10 days but by the time I got 10/11 months in I could do 200mg for 12 days no problem. When I say "no problem" I mean no wildly fluctuating mood swings or nasty depressive episodes, just feeling a bit tearful, a bit tired and a bit out of sorts! I use the 200mg utro vaginally - right from day 1 - there was no way I would swallow the things!
I was also prescribed testosterone in February 2019 and this dealt with the underlying fatigue, brain fog and libido issues which the gel and the utro did not solve on their own but that also took 3/4 months to resolve itself.
In my case now I am 15 months in I can actually say that by and large I fell better than I have in 20 years but it has taken all that time to even out and become consistent. There are still fluctuations but they are mild compared to what I had before and on other hrt medications. I am of the opinion that hrt is a very slow burn for some women which is unfortunate because the roller coaster which I had to go through to get to where I am today - it would have been easy to give up and assume it wouldn't happen. In my case I felt I had no choice - continue with the way things were (no life at all!) or keep going in the hope there would be light at the end of the tunnel.
When I was bad I had insomnia, panic attacks that made me nearly certifiable, a mind like a washing machine, or a complete blank, pains all over my body so much so a consultant diagnosed me with fibromyalgia! When I wasn't hyped to the max I couldn't get out of bed. I had acid reflux, felt like I couldn't see properly. In fact it is easier to say what I didn't have of the meno menu - which was vaginal atrophy. This had gone on for over 5 years! So therefore Redlocks - all I would say is that there is success but it can be a long and tortuous experience. I think sometimes it is even over estimated by experienced and respected consultants just what a mess we can be and how long it will take for some form of hrt to fix it.
Good luck and much love xx
