Hi Warwick
hope that helps.
In terms of the dizziness. That could be caused by lots of things, not just the HRT.
It could be fluctuations in your blood pressure.
If your BP is lowish then a small fluctuation might give you that woozy feeling.
As I've mentioned before a lot of AD's can have this affect and reduce peoples BP without them realising it.
Even a bad head cold can have an effect on our ears and balance.
If your unsure on the BP front it might be an idea getting a small home BP testing machine.
When you feel woozy, see what your BP is reading.
Also have you been tested recently for anaemia? This can also leave you feeling dizzy and often people arent breathless with it. Having anaemia can also make your heart work harder and give you a sense that its racing faster than normal.
Hope that gives a few more things to maybe consider. Glad the patches are helping though.
Let us know if the earlier change starts to help too
