How did you get on at your WI raudi???
I have been unsure about core and my WW leader said that watever plan we choose we need to do it for the whole week and not swop plans halfway through a week, so I decided not to do core at the moment!! Was interested to notice that plain ryvita is allowed on core, but any of the other ryvitas have to be taken from your weekly points allowance...
I think I might do points for a month, then core for 2 weeks, then points again and try to keep the variety that way!
