Lovely to read you Robin, but sorry you've been unwell...  this cold weather is lingering this year, isn't it!  
Scrumps - like you, the Dukan way isn't making the kilos melt off as once it would for me either (and if today was Friday, I'd be registering a gain!)!  Unlike you from the sounds of it, I probably eat too much but I still have issues eating in public when others are noshing their main course, often two pieces of fruit, then yoghurt.  I like to be chewing while they are!  Not watching them eat their puds when I've long finished!  I guess I could eat at my desk on my own (yawn!!).  awhhhh!
