Thanks guys. I think the main thing that worries me is the full bladder. I have never been able to hold on for very long. Its not that I pee myself if I hold on too long, its more that I find it so painful and my muscles cramp up so much that I struggle to then be able to pee at all. Then I end up with bladder infections. This has been a problem for me since I was a little kid.
My DH says I am going to have to learn to toughen up and learn to hold on. I am worried about my 18 week scan as they said I need to have a fuller bladder than I did for my 12 week scan. I am wondering if you can train your bladder to hold for longer? If so how do you do this without causing bladder infections?

Ok just finished my first 750ml bottle and about to make my second! I mix lemon cordial with it, cause I really hate drinking water by itself.
