Thanks mumat that article is really helpful, just the sort of thing I needed to read. Very enlightening as well that as a rough benchmark maintenance level is likely to be in the region of 150g carbs/day. I am prob having about 20-40 depending on the day at the moment, so there's a lot of room to expand the veg/nut/seed repetoire and add a bit of fruit. I bit the bullet and had some broad beans with my (otherwise very low carb!) dinner 
Thanks also for the post about GI/GL considerations timidviper, that is a really sensible idea. I think in my head I assume that GI and carbyness is pretty much the same thing, but having scanned though a few GI tables, it's really not, there are some surprises in there, like how low on the scale things like plums are for example (24) compared to strawbs (40) when strawberries are the lower in carbs. Similarly hummus scores a tiny and exemplary 6 on the GI index but is really quite carby due to the chickpeas.
So I think my intentions based on combining the LCHF philosophy, GI information, primal ideology and my own reasons for actually starting out are to eat whatever I want from veg (and lots of it, both quantity and variety), to freely include nuts and seeds, to have lots of animal products (meat, fish, fat, dairy), to include fruits like I used to have cakes/biscuits, so as a once or twice a day sweet treat, and to bring in moderate amounts of pulses. And then see what happens. Staying away from refined grains/potatoes (largely) but occasional small tastes will not make the skies fall in. I have been regarding flour/pasta etc as poison (whilst weaning myself away from them, continually telling myself they are EVIL and will ruin my body) and realise that is neurotic. They just should not form a major or even daily part of my diet.
This thread has been brilliant, lots of great ideas, food inspiration, knowledgable folk and has really helped me do the tough bit at the start of going cold turkey on the carbs 
By the way BIWI you were right, I no longer am fussed over golden syrup sandwiches, though I would cheerfully have killed for one two weeks ago.
My diabetic father has been following what I've been doing and reading about it, (he loved the Food Revolution video) and is now starting to bring down his carbs. I got a phonecall at lunchtime asking how exactly to do cauliflower rice to go with their chilli
I am spreading the word!
