Good going! Tomorrow's my last day of 810. Weird to hear your experience...I felt tickety-boo all week. The only problem I had was with washing up! I was a bit hungry yesterday (had no idea what for and it soon passed) but really don't feel like I came out of ketosis. I found it worked better for me when I ate in the evening when I still had two food packs to go (and no - I didn't feel hungry all day at work - my brain felt like it was on SS cos I stuck to the same daytime routine) - the two times I ate in the morning - I sort of got a bit 'nibbly'
