Hi Polpringle,
When I started HRT I felt exactly the same. I started on 25 mcg patch.
I initially started it because of sleep problems but it made me wiry and jittery, and seemed to have the opposite effect.
After a few weeks it settled down and things improved greatly. Start low, go slow and give it time.
It takes a while for the body to adapt.
Hope this helps
cheers
