Everything in moderation I believe in... and a day off (also moderation) can keep you on track.
Have you tried other sweet things?
I believe on SW little meringue nexts are low syn I had them all the time with yog and berries.
Choc Shot on the fresh berries?
Also try buying the frozen berries/summer fruits amazingly sweet defrosted with natural yog!
It's definitely advised to use syns if you aren't like mentioned!
BUT all aside I think most people are guilty of just going **** it. Hey you've done it, don't give yourself a hard time just move on from it
