The 'honeymoon period' in marriage lasts for 13 months and seven days, according to new research.
Getting too comfortable around each other, the initial excitement wearing off and knowing each other better are the main reasons.
Three in 10 blame "sheer laziness" as a romance killer but before women raise their eyebrows - they're more likely than men to stop making an effort.
The survey, conducted by market researchers OnePoll, quizzed 2,000 married Brits on the highs and lows of matrimony.
Not bothering to look good for our partner, bickering more often and a dip in our sex lives were voted the biggest tell-tale signs the honeymoon is over.
We're also more honest about the things we don't want to do any more - refusing to visit restaurants our partners prefer or sit through films we find boring just to please.
But it's not all doom and gloom - seven in 10 believe the spark can be rekindled after the initial burn-out.
Listening to each other more was voted the best way to reignite the magic, followed by a romantic holiday and more date nights.
OnePoll spokesman Kevin Smith said: "It's not uncommon for the initial excitement for newlyweds to wear off after some time.
"The patterns are very similar - less sex, more arguments. These are completely natural things to happen over time in any relationship.
"People shouldn't feel disheartened when the initial buzz of being married wears off. It's more uncommon for the honeymoon period to last forever."
Feeling more settled, knowing our partners more intimately and not having to look perfect 24/7 were voted the best perks of the inevitable. Being more comfortable to talk about our problems was also a firm favourite.
But taking each other for granted, being annoyed by their irritating habits and feeling less excited to see our partners are the top lows of the honeymoon being over.
Kevin Smith added: "Romance is out there for all of us to rekindle, we just have to take the jump and grasp it back.
In some cases relationships are better once the honeymoon is over - we can finally be ourselves and not have to worry about pleasing someone else 24/7".
