Good luck - hope it helps
I found it got rid of the interminable itch I had had for 4 years, even when still on the pill (that was probably the wrong sort of oestrogen) and I have not resorted to slapping body shop hand cream on my desperately dry outside bits since
It is not perfect for the bladder problems but definitely makes a difference - I have found that addition of full low dose hrt helped. It stopped the random infections which did not help matters.
I have found that, in addition, drinking plenty of water during the day helps - it dilutes the urine, making it less irritating, and stretches the bladder, so it is less likely to spasm. I started doing this after a kidney stone, and it reduced the number of times I needed to get up in the night.
I drink an occasional cup of fresh brewed cafetiere coffee, but instant should be avoided at all costs, even 'decaffeinated'. Guaranteed to end in disaster.
