Firstly, well done you!! You've done the hardest bit, which is deciding to do CD and managing the first week. You will have lost a significant amount of weight - I weighed 18st and lost 11lb in my first week....
As our friends above have already said, things do slow down SIGNIFICANTLY in the pooing dept... Just make sure you are drinking at least your 2.5 litres per day. I drink 4, and it does help. Definitely get some of the approved CD fibre as it will sort you out.
DO keep at it. You will have plenty of support from so many of us on here. I find reading about others' losses and seeing pictures so motivating, and it certainly has got me this far... (3 weeks in, 19lb lost to date). A fair while for me to go, but I'm not stopping now.
You can do this.
It would be great if your counsellor could see you more often, or maybe get a friend to bring round some scales once a week so you can see your losses, and feel great about yourself.
You deserve to!
Best of luck, and keep at it.
