Hiya Maz, I've just switched from CD to SW and i'm currently on day 4. Not lost anything so far but didn't really stick to it much on the first couple of days due to not having the right type of food in the house. I put on 2lbs after stopping CD due to my glycogen stores re-loading. TBH i'm not expecting too much on SW as I can't get my head around eating so much and yet still losing weight, i'm just trying to maintain whilst i'm off CD so anything I lose will be a bonus and I can't be disappointed.
I weigh in on Saturdays so it will be interesting to see my results this week.
I'm sure you'll do fine on SW, losing the last few pounds slower will be better for maintaining in the long run.
