I seem to manage alright on my fasts, but then I've been doing it since August. Lots of water today, though it's really cold so I might have a couple of weak hot blackcurrent squashes and a low cal hot choc later on.
After the amount of dinner I ate yesterday (and snacks in the day) I'm glad to be fasting today! Looking forward to my dinner though as I prepped my low cal lasagne yesterday, yum!
