I’m doing a VLCD diet (exante). Lost around a stone in first month. But every so often I fall off the wagon, e.g. on Friday I ate normally all day coz I was utterly fed up and lost all my motivation. I went straight back on it on Saturday though. However, I now feel shit- headaches, fatigue, etc. Is it pretty much like going back to the first three days? It kind of feels like that. Have other people experienced the same?
