Thank you everyone for your kind words and support - you're all very lovely!
In the end, I felt so rough that I toddled off to bed at around 9pm, slept for pretty much TWELVE hours solid, had a good... er.... *cough* "empty out" this morning and then went to do two day's worth of poo-picking (140!!!!) from the horses field. Just had a late, but small, porridge brekkie... so actually fasted for 21 hours, unintentionally. Employer is having a lunch party today so I'm off shortly to wait the table for her 12 guests so I'll be burning off more whizzing around on my feet than my usual relaxing Sunday. The scales weren't too hard on me this morning (for me, the next day is deffo the one that shows the damage rather than 48 hours), especially as I'd actually lost a couple of pounds last week anyway. Still, back to being good again now.
Looking back, the lovely taste of all those carbs definitely wasn't worth all that discomfort, so I can categorically state for the record that I WON'T be bingeing again!!!! "Moderation" will now be my key word!
