Hi Dawn, yep! I'm really pleased as I haven't found it that difficult - am well and truly "in the zone!".
I drink around 3 - 3.5 litres of fluid a day, sounds a lot but that's not just plain water but includes 1-2 cans of coke zero, a couple of mugs of coffee and I always make my shakes with 500mls of water which also helps. At least 2 litres is plain water though.
Also, I always have a bar for breakfast but I don't have it until I have drank at least 750ml of water (i have those bottled water sports bottles which I refill) and that gets things off to a really good start every day. My first week I wasn't drinking anywhere near that but its easy now and I don't have to try too hard. Also (apols if TMI) my body seems used to it and I don't have to wee as often!!
