I'm on day 3 of CD SS+ and I didn't feel any real hunger until last night. It continued this morning but I also felt very weak (even after my shake). I did a stick test and tested positive for ketones (on the brand I use there are 4 'levels', 4 being the highest, and I was between 3 and 4). However I am feeling hungry (had my 2nd shake an hour ago) and a little weak. Is this normal and will it go because I had thought it was just getting into ketosis that this happened?
