The feeling when you've doggedly pursued a healthy lifestyle (for 1 day-forever) and then your work pals invite you for an afterwork drink... and you realise one pint will ruin everything.
Internal monologue: I really want to go out and have fun but I'm already feeling pub guilt - an internal dreading of huge amounts of calories and naughty additives that will ruin my attempts at being healthy.
I'll just go home - can't face the pub guilt.
I can't come out - I'm going to the gym. Best to avoid the pub guilt.
