I completely agree, it's definitely essential to have a few syns every day, for all the reasons everyone else has said - and, as PatchworkPuss said, it's not hard to do, just 250ml of orange/ apple juice, or a level tbsp of butter stirred into your dinner, or a small glass of wine, or a small bag of walkers baked - the list goes on and on - would get you to 5 or 6, for example, so I'm sure you could find something you'd really enjoy and would easily slot into your life.
Another reason it's important, is that you don't confuse your body into thinking it should be in starvation mode, which is when you start storing fat, and that's when you stop losing weight, of course.
If you can get away with just 5 a day, that's great, but, it will become harder and harder to lose weight as you get closer to your target, so if you're only have 0 to 5 at the moment, that doesn't leave you anywhere to go, so definitely worth trying to find some way of having a few syns a day.
Lucky you, though, I'd love to be able to "forced" to find some naughty things to eat!
Good luck
