Ketosis already?!!

So I am halfway through day 3 and feeling fab, also had a very good day yesterday too! Could I possibly be in ketosis already? I see food around me but don't want nor need it, I have made sandwiches and dinners for the family and not even wanted a tiny nibble! Day 1 was a struggle as I felt full, sick and dizzy most of the afternoon and evening and had a major craving for quorn chicken before I went to bed lol! But nothing since....

It is possible. I was getting results on Ketostix in the early evening of my second day.

I was in Ketosis by day three

I'm on day 3 and I have the beginings of a claggy mouth. Felt a bit hungry but I think it's more psychological than physical.
