Have you been hob mobbing with he queen???
Had a giggle as I read this (sorry!!) as I just listed to the news and it made a big thing of the queen suffering from a stomach bug!! (She is 86 i suppose!)
As for your question just sip water a till your stomach is settled then just get back on plan forget the lucozade it's been and gone and just remember you had nothing else so that was your daily allowance ( I know not technically SW but hei Ho part of life!)
Hope your better soon
