Confusion on flexi Syns

I have noticed on here that people are confused what is meant by flexi Syns so i will clarify.
Taken straight from the book
FLEXI SYNS
"Question. What if I need more Syns?
Answer. If 5 - 15 Syns a day is where you need to be on a regular basis, but sometimes it's just too tight for comfort, then use another unique Slimming World tool - flexible syns! It's far better to allow yourself extra syns every now and again without the punishment of reducing your syns the next day to compensate. There really is no need to suffer. Just keep counting to an allocated upper limit and stay in control"
When should I use Flexi syns ?
"There is plenty of evidence that allowing yourself to be a little more flexible when you need is the key to long term success. Flexi syns are the safety valve you can use when you feel that otherwise you might give in and lose control. "
These flexi syn days are for the odd occasions such as birthdays weddings etc. You can increase your daily syns to 20, 30, 40 or even 50 but keep counting and set your upper limit before you go out.
I hope that clears it up for you all x

Brilliantly clear post. Nothing much to add, I just didn't want it to disappear off the first page, until everyone has had a chance to read it and refresh their memories.

Thanks again for posting this!!!!
