Hello shandyAndy,

Nice name...I could just drink a shandy!

My vote goes for folklore. Our digestive system does not go to sleep. The evidence is that most people go to the loo first thing in the morning - after the digestive system has been labouring away while we sleep!

I lived in Spain for years and people there often eat their main meal at 10 or 11 at night - and they aren't overweight.

Thsi is not to say it is a good idea to go to bed with a stomach full. I just think it may not make any difference.

regards,

Robert
