Hi ya Lacie
Welcome to the board!
It is best to join a class if you can, as i find it much better than doing it on my own.
It costs £5 to join (i think) and then £4.50 a week, It is expensive but it is well worth it, i really look forward to going, its nice to get support and the ladies (and a few men!) are lovely and really helpful.
If you wanted to do it at home you can, just see if you can get hold of the books on ebay, or join slimming world to get the books and if you dont want to go anymore then just dont turn up or something?
As i said though the classes are great, you get awards for when you lose half a stone, then a stone etc etc and slimmer of the week is great, iv won it twice!
On the slimming world website there is a box you can put your postcode in and it will tell you where your nearest classes are, see if you can pop along to one of them.
Also when you join you will get the password to the site every week and that is great!
There is also a way you can do it online, but im not sure how that works!
Good luck xxxxx
