I think I found my "groove" again

Thought I'd better write some more to keep up to date. I've been struggling to get back into my fitness regime for some months now. Since moving to Portugal in 2005 I've been so into fitness and was on a great , achievable diet and by mid 2006 had managed a serious weight loss. Then, like so many others, I wenmt off the rails - I get complaincant when I've lost the weight and think I can eat anything I want and drink too much, but you can't it's ongoing. Anyway by November 2006 and got all serious again and had a great personal trainer who encouraged me and supported me and again, by mid 2007 was looking wonderful. Very fit and probably the slimmest I've been in my adult life, but again I lost my groove. You can see the pattern now can't you? I know I'm not alone, others do this too, and I know it's "normal", but I hate it and I start to beat myself up, then my self esteem takes a dive, then the motivation goes. That's the worst bit. And for months now, I have planned my big come back regime and it's fallen by the wayside, but today I hit the gym (at home in the garage) with a renewed vigour. It was cold and raining, but I wrapped up and I ran and I did my weights programme and I feel great. I have a saying that "once you get your head around it, your arse will follow....". I think I'm there, my head is sorted and I'm going for it.
I'm going to enlist the advice of a personal trainer for some added motivation and keep my fitness diary, and ofcourse I'll update you here.

Looking at size 12 for March (yes 2009).
