Hi new to this, I've just started the cambridge diet SS. I started yesterday and got through the day ok however today has been horrible. I feel so sick and have no energy! Is this normal? I've been reading threads and people are saying it will get better! But when? I really am giving this diet 100% and don't want to give up so early! Anyone else felt like this and when did things start to get better? Also does anyone know when I will be in ketosis and how do you know if you are? Thanks in advance!
