Ah yes. I know that feeling, londonlottie. All I can say, from my own experience, is that when you realise you have to do it, somehow your head gets in the zone. I've faffed around with it for so long, I'm embarrassed to call myself a low carber, really!
There's something different that triggers the motivation for all of us. It is pointless me telling you to do it, because you need to feel it for yourself.
For me, it was the fact that I have a weekend in Rome coming up, with my DH, in June. When I realised that all I was thinking about, on Christmas Day, when he handed me this present, was what would I wear, and how would I stop my thighs chafing together in the heat? 
That, plus a planned fortnight in Barbados in August - with the inevitable "what will I wear by the pool/I will look like a beached whale again" dialogue in my head - was what really galvanised me to get back on the low carb wagon properly.
And this bootcamp is based on what I've pilfered from various low carb plans over the years. (With the exception of Durkan, because I think that's a very dubious approach)
But you have the advantage over many who are on this bootcamp in that you know what you're doing. You know about fat/water, etc.
