To have never realised this was normal?

To feel really drowsy after lunch? I thought it was just me but I’ve just read it’s totally normal and everyone gets tired after lunch!

The blood rushes to the digestive system after food so there’s less in the brain
hence drowsy
one of the reasons some countries have a siesta ( it’s not just to do with the weather )

It’s the carbs. Carbs make you sleepy, it’s why people fall asleep after a big Sunday Lunch. If you don’t have carbs at lunch you won’t feel dozy.

I only get it if I eat a bigger meal - usually I have a sandwich or something and have a big meal in the evening, but if I have a pizza with colleagues or go out for a meal on a day off, I get very sleepy around 3pm.

I’m another one whose sleep isn’t affected by caffeine. I actually sleep really badly so gave up caffeine completely for a year and didn’t experience any improvement whatsoever!

I steer clear of carbs at lunchtime for this reason. Means I'm usually starving around 4pm but can cope with a piece of toast fine by then!

Isn’t dumping syndrome a side effect of gastric bypass?! It’s like nausea, vomiting, sweating, getting the shits. A bit more severe than post-lunch fatigues.

It's called Dumping Syndrome. My OH was like this and his grandfather is famed for his head falling into his custard!

Dumping syndrome is something totally different!

I didn’t know this was a thing and have never experienced it.

Redpeach · 03/06/2025 13:40

It can be avoided with the right food choices

I have never had this. How weird!

TheFlis · 03/06/2025 13:38

I used to get this but it stopped when I went low carb.

Yes coffee always makes me sleepy too! I always have one before bedtime which seems weird!

Same here!! I often have a coffee before bed, never stops me sleeping or gives me any sort of jitters, day or night.

Depends what you are eating to an extent but generally yes.

Same, coffee never stops me sleeping, apparently is a sign of ADHD (but sure so is everything now a days)

Coffee helps my husband to sleep!

If you go to conferences, the first slot after lunch is called the Graveyard slot because of this. .
