I have done slimming world before but I am having trouble really being strict with myself. I went to the classes before but I am not able to this time due to other commitments. I am finding it hard not to have a glass of wine at the end of the day. How many syns is a glass ( a large glass!) Any advice is appreciated. i just don't want to be overweight when I get married to my childhood sweetheart! I'm prob a size 14. None of my clothes fit me! I have a running machine and have cycled and gone swimming but after a back operation, the activities sometimes aggravates my back.
