Hillary Clinton and Donald Trump go head-to-head for the first time from 2am Irish time
After months of separate but acrimonious campaigning, Hillary Clinton and Donald Trump will finally go head-to-head overnight in the first of three televised US presidential debates.
The debate gets underway at 2am Irish time, and is set to last 90 minutes - so if you do decide to watch live, you'll be in for a very late night / early morning.
Luckily, anybody who does want to stay up will be very well covered.
Irish viewers can tune in to BBC, Sky News or Channel 4 for live coverage.
Many major US media outlets will also be streaming the debate live.
NBC News, PBS, Fox News, Politico, The Washington Post, Bloomberg and others will be streaming via their websites and/or YouTube.
Many sites are dropping their usual sign-in procedures for the debate - which will have no ad breaks - although you still might encounter a few region locked sites if you're unlucky.
However, such restrictions hopefully won't apply to most of the YouTube streams - you can find out more about their streams here.
Social media will inevitably be hopping during, before and after the debate, so it's no surprise that the giants of that sphere are getting involved too.
If you really want something different, you could always check out the debate in virtual reality.
For those who don't fancy staying up until the early hours of the morning, Democrats Abroad Ireland are hosting a screening of the debate and a discussion at the Arlington Hotel, Bachelors Walk in Dublin from 7pm tomorrow evening.
Of course, you won't be able to browse the web or turn on the radio or TV tomorrow morning without hearing everything about what could well be a very colourful 90 minutes indeed.
