Really, it's not.
My poor tum tum appears to have reacted badly to something I've eaten, but I don't know what. It's been unsettled for the last couple of days, and I really have no idea why; not a drop of alcohol has passed my lips yet my stomach is behaving as though I've had 10 pints of Gold every night.
This also meant I did not get a run in this morning – which means, common sense tells me, I am not running a marathon next week. I've emailed one of the organisers to see if I can 'downgrade' the race to a half marathon instead, fingers crossed I can.
I'm still eating just two meals a day here, that's all you need with a snackette somewhere in the middle. Funnily enough, though, I don't really feel any lighter...
