I’ve actually been thinking about starting a separate thread about this. Might do so during my sofa time. Basically I’ve started to connect the dots to suspect that strong hangover rides are actually far more down to all the extra carbs we tend to eat on a night out. Easily 3x the calorie count of a normal dinner and made up of mostly bread or potatoes or similar.
EDIT: thread started here: The 'off leash' hangover ride phenomenon (is it actually about carbs?)
