Not being able to sleep at night is not only frustrating, but usually makes you grumpy and bad-tempered the next morning too.
In the long-term, dealing with a lack of sleep can also impact on your health and your waistline - especially if you're having a midnight snack on the foods to avoid before bed.
Plus just an hour's less shut-eye a night means you're more likely to snack on sugary, salty junk food the following day to help keep you awake.
And what you eat before putting on your pyjamas can make all the difference to how well you'll sleep full stop. These are 10 foods to avoid before bed if you want to get a restful night's sleep...
10 foods to avoid before bed
Beans on toast
They're renowned for making you windy because they're slow to digest, so it's not a good idea to eat beans before bed if you want to a deep sleep. Bread, especially the white, processed stuff, is also best avoided because the sugar will cause an energy spike.
Bacon and eggs
Save your bacon and eggs for breakfast if you want to get your full eight hours. Greasy food, especially red meat, is hard for the body to breakdown so your stomach will be making all sorts of funny noises.

Ice-cream
Had a bad day? Don't reach for the ice-cream! It's packed with fat and sugar, not what your body or brain need to relax after a long day.
Cheese and crackers
That old-wives tale that you shouldn't eat cheese before bed does hold some truth. It might not necessarily give you nightmares, but it might well keep you up thanks to a chemical in cheese that makes your brain work even harder.
Pizza
We're all guilty of tucking in to a late night pizza with the other half in front of the telly, but it's probably to blame when you can't nod off a few hours later - and not just thanks to indigestion.
Large meals might make you feel tired, but when you lie down your poor tummy will be doing somersaults trying to break down all those stodgy carbs. Eat a slice at lunchtime instead.
Curry
Say no to spicy food before bed unless you want to be kept awake by heartburn, bloating and wind. Not pleasant, especially for the poor person that you have to share a duvet with!
Cereal
We're definitely guilty of filling up on this one as a midnight treat! Lots of cereals contain barley, oats and bran which slow down digestion. Warm milk is a much more tummy-soothing option.
Sweets
Drift off more easily by saving the sugary sweets for the school run when you really need an energy boost.
Dark chocolate
Sleep-zapping caffeine is not just hiding in tea, coffee, cola or energy drinks. It's also lurking in dark chocolate. Swap your fix for a couple of squares of white chocolate instead and still satisfy that sweet tooth.
Garlic
Heartburn, indigestion and acid reflux - sleep much more easily by steering clear of garlic at dinner time.
