Don't go to bed! It's not done in the swimming yet, so keep your trunks on. Jonathan Fox defends his title in the 100 backstroke within the hour.
A win would make it a hat-trick of gold for GB on day one in the Pool. He's favourite but Brazil have Italo Pereira in Lane five.
And the roar in here is worth at least a length or two...
Men’s S13 100m Butterfly final
Belarus swimmer Ihar Boki's has been dubbed a gold medal factory to rival American Michael Phelps and he's notched his first of these Games.
The 22-year-old, who won five golds at London 2012, eases to victory in the men’s S13 100m Butterfly final in a new world record time as well.
More medals to come from Boki you suspect.
We are coming up to one of those brilliantly chaotic phases of the evening. So, let's keep you all in the loop. This is the plan.
Georgina Hermitage starts her track campaign in the women's 100m T37 event just before midnight, while Britain's Andrew Mullen is in the men's 200m freestyle S5 final in the swimming pool.
Mullen, who qualified third fastest for the final, has a tough task as he is up against home favourite, Paralympics poster boy, world record holder and fastest qualifier Daniel Dias of Brazil.
The British trio of Olivia Breen, Sophie Hahn and Kadeena Cox go in the heats of the women's 100m T38.
Jon Fox could well claim a medal in the men's 100m backstroke at 00:32 BST, although he has been struggling with a shoulder injury for the last few months. In the table tennis, Ross Wilson and Sue Gilroy are in action.
Got all that? Good. Don't worry, I won't be testing you. Far too late for that.
Men's S5 200m freestyle final (23:59 BST)
Daniel Dias is Brazil's home favourite, the posterboy and tipped to lead his country's charge for gold.
But Britain's Andrew Mullen is out to spoil the party.
"I don't care who you are or how fast you are, I've come here to win," he said after finishing third in the morning's heats, four seconds behind Dias at the top of the leaderboard.
Will Mullen come back in the final and fulfill his promise?

Men's T13 100m heats
Ireland's Jason Smyth got off to a flying start in his T13 100m heat as he clocked a time of 10.76 seconds.
The fastest Paralympian on the planet showed blistering pace from the blocks as he left too much work for Namibia's Johannes Nambala to catch him.

BBC Sport's Paralympics reporter in Rio

Both have more events to come this week, while Firth, who represented Ireland and won gold at the London Paralympics, believes the British team can now go on to have a brilliant Paralympics in Rio.

Women's 100m T53
Earlier on tonight, Great Britain's Sammi Kinghorn finished fifth in her first ever Paralympic final as China's Lisha Huang claimed gold in a time of 16.28 seconds.
Kinghorn failed to win a medal in the women's T53 100m final but the 20-year-old is pleased with how her career is progressing.
She told BBC Radio 5 live: "I'm so pleased with all the support I've had and I couldn't do it without them.

We mentioned that American Tatyana McFadden was aiming for a sweep of seven golds in Rio.
Well, those hopes are still alive as she qualified for the final, although she did suffer a surprising defeat in her women's 100m T54 heat.
China's Liu Wenjun pulled away from the three-time Paralympic champion as she clocked 16.00 seconds with McFadden following in 16.52.

Beth Firth, speaking to Channel 4: "I'm so chuffed with that but I couldn't have done it without the support of everyone back home - especially my church and my family.
"God puts challenges in your way but shows you a path if you work hard and put your mind to it. Hopefully there's many more medals to come for the rest of the team."
Swimming: Women's T53 100m final

Graham Edmunds
Paralympic swimming gold medal winner on BBC Radio 5 live
It's been a brilliant night in the pool.
The GB guys have come out here and shown what they can do. It's amazing to see Beth Firth break the world record again.
Swimming: Women's T53 100m final
Although she's a way behind Beth Firth there's a bronze medal for Great Britain's Jessica-Jane Applegate as well.
This isn't the 20-year-old's favoured event, though, and she will hope to defend the gold she won in the women's S14 200m freestyle at London 2012.

It is gold for Great Britain - the fifth of the night.
Beth Firth has successfully defended the women's S14 100m backstroke and it's a new world record time as well.
The 20-year-old from County Down actually broke her own world record in the heats, and she has gone even quicker to break it again in the final.
Firth swam for Ireland at London 2012 before switching to represent Great Britain a year later.

The woman to beat is certainly Great Britain's Bethany Firth, who set a new world record of one minute 4.53 seconds earlier today.
Is there another gold for Britain coming now?
