Thanks Matt. Bit worried as I just had the second sachet and had to use the loo immediately. Yet by now I would have thought it would be clear liquid going down the loo but TMI, it is still very dark. Worried the last sachet won't have any effect and will continue to stay the same colour. Don't want to be turned away tomorrow but there is nothing I can do. I am not going to the toilet as much as I thought either, been about 5-6 times. Like I say, if it doesn't turn clear, I just hope they don't send me away. Can't bear the thought of that :(
