Hi Fizwhizz. I sympathise - that feeling that the colour has drained out of the world is one of the reasons I went on HRT (as well as frequent headaches, VA, lost libido, tinnitus, creaky joints...) my sleep was OK though
Walking/running/being out in a park or somewhere green did help up to a point, but it also made me sad that I wasn't getting the buzz out of it that I used to, if you know what I mean.
I'm currently on tibolone and it's working very well for me. I'm on it because I have very bleedy fibroids that didn't like conventional HRT (plus I felt very bloated on 50mcg patch and utrogestan). I believe it's the androgenic component of tibolone that is very good for 'blunted motivation' as I saw it described somewhere. I've not had a whoosh of energy but I feel much more resilient and optimistic and like my normal self again - it's also helped relieve all the other symptoms which obviously helps with mood. And I've had no side effects.
Is tibolone contraindicated if you have thyroid issues? It works in a different way to oestrogen/progesterone though so perhaps you could try it sooner rather than later.
