Sorry to hear you're feeling rubbish Jem, anything you can think might be to blame? I feel like like at times, usually during TOTM and also when I'm ovulating (sorry if TMI!).
If you're not hungry, don't eat now, maybe have a bigger breakfast - I know we're not supposed to carry points over but rationally, how can it hurt, esp if you've skipped a meal & are well within points? Hope you feel better soon xx
