I have been on S & S now for 8 days only traces of ketones and thought I would have been in full ketosis by now, I did have a slip on day 3 as felt so bad, but been on track since with 2 shakes 1 meal and one bar per day with plenty of water, would be grateful for any advice. Feeling better now than last week when I thought I would faint lol, but still not sure why I am not in full ketosis and still hungry at times. Thanks.
