I think you will be feeling much more full of energy tomorrow. I have my fingers crossed anyway! And I suppose anything that can make you feel more on the ball..caffeine, but not too much? I can't do that as it contributes to my migraines.
As to explaining it...well I haven't told anyone as yet, bar my OH. I don't want the negative comments. I mean, I know this is an extreme diet - so the pros are extreme, and so are the cons. I'm not stupid and I don't want to be told I am. I am working from home at the minute so it's OK. If I have to have a shake while I'm out, I'll tell people it's a protein shake. Obviously I'm going to have to tell people at some point, but I'm not doing it now!
