Ok I know it sounds great, but I am a little concerned. I am normally the kind of person who sniffs a mars bar and gains 2 pounds, but at the moment, although most of my main meals are fairly healthy, I eat chocolate after school every day, eat cakes and loads of bread at home. Now only am I not gaining weight, but I am losing it. I am currently taking citalopram for depression/anxiety, but the last time I was on this I gained loads of weight. I have been tested for over-active thyroid as my mum had that, but levels are normal. Any otehr guesses, or should I just enjoy it???
