Awww Petal, thankyou so much for asking.
I've got an appointment on Monday to have some blood tests done, about 8 of them !!!
I've been on my ' lady-time ' now for over a fortnight with no sign of it getting any lighter. The doctor said that it's highly possible that the drinking is related to the hormone imbalance and the stress it brings.
Why they can't do BT's at the docs I don't know, I've got to go to the hospital. Again, thanks for asking and will let you know when I get the results.
