Just a moment when I thought, "know what, a couple of days off might be just what I need."
Somehow Belgium and the United States turned the final last 16 game into an exhilarating, exhausting delight.
Fantastic to watch. But even neutrals like me were left knackered by the relentless commitment of it all.
Had the second stage matches lost a little of the steam that Brazil 2014 had been building from almost the first kick of the ball?
Certainly the goal average dropped. And while some of the games were tight, the eagle-eyed punter on www.sportsbettinginfo.com will have noted that form asserted itself - all the group winners progressed to the quarter finals for the first time since the advent of a 32 team tournament.
And yet. There at the last Belgium and the US were battering each other with any and every ounce of energy they had. Tim Howard making more saves that any other World Cup goalkeeper. The US pulling a reverse Alamo on the Belgian goal in a riveting but ultimately futile second half of extra time.
So I felt like I needed a break. A feeling that lasted right through until I woke up on Wednesday and mournfully realised the next match was more than 48 hours away.
The wait's almost over though. And it looks like being worth it.
France v Germany.
Brazil v Colombia.
Didier Deschamps v Joachim Low.
Neymar v James Rodríguez.
Few people would think you daft if you said the winner of either of these games could win the tournament. But I'd defy you to predict who that might be with any confidence.
Colombia have impressed but they've impressed so far in games that don't carry the same pressure that will come with playing Brazil in Brazil during a World Cup.
And Brazil have kept finding ways to win despite being under the constant pressure of being Brazil at a World Cup held in Brazil.
France, with the hissy fit, toys out of the pram nonsense of 2010 long behind them, have progressed pretty serenely. 10 goals scored and just two conceded in four games.
Germany have scored nine and conceded three. But they needed extra time to find a way past Algeria and are now contending with an outbreak of 'flu.
Brazil, of course, remain favourites to overcome Colombia and to lift the trophy.
But I'm as gloriously confused as I have been since the start.
Will Neymar, home advantage and a determination to believe in destiny be enough for Brazil?
Perhaps. Perhaps not. Colombia have often looked inspired as a team. James Rodriguez has rarely looked anything else. The current top scorer against the current favourites.
The natural narrative still suggests this is a World Cup for Brazil to win. But tonight we'll see three other teams with their own destiny to believe in.
It's tome to be amazed, enthralled and knackered all over again.
