We started weight loss classes at the same time. She has lost twice as much weight as me. ( she is two stone heavier than me) at first I was really pleased for her. But now when I ask her how she thinks she has done each week, she rattles off loads of food she has eaten, while I have been very saintly! She has also just started taking thyroxine for her under active thyroid, so I said that this is probably helping. She has just come from a check up to announce that she is losing weight naturally not from the drugs. I love my sis and want her to do well and her health issues to improve, but the nasty little side of me is a green eyed starving monster! Just writing this has helped me get it off my chest. Rant over.
