Sorry - I never got back here yesterday. Work intervened grrrr!
If you look at my signature carefully, you'll see that I lost my weight with "healthy eating" between March 2002 and December 2003, and only turned to Dukan in November 2007 after I quit smoking and regained some weight, and could only get to a certain weight with healthy eating without losing the plot again
Ketosis helps me no end with my weight but, because I've never resolved the real issues (ie the compulsive eating / binge eating), once out of ketosis, and without my crutch, things are tough for me. This is a common problem for people who've been VERY overweight. You'll be fine!
Just stick around here, and plan to stick to Conso to the letter...
