Lando Norris has revealed that he was "heavily dosed up" on painkillers during the United States Grand Prix after struggling with headaches throughout the weekend, an issue he has attributed to the bumpiness of the track.
The Briton finished the race in P6 – the same position from which he started – after keeping rivals including Fernando Alonso at bay.
When speaking to the media after the race, Norris was asked by RacingNews365.com how it feels to push another driver into a mistake, leading him to admit that he was too busy trying to focus through the pain he was experiencing during the race.
"There was so much focus [in] the last 10 laps, especially on the track like this," Norris explained.
"There's so many bumps. I was heavily dosed up on headache tablets because I struggled a lot with that this weekend, because it's bumpy."
Norris wary of making mistakes at COTA
Norris admits that his headaches left him more cautious of the possiblity of making a mistake.
"It's really not nice," he said of the impact.
"I don't know if it's better for us or worse for us than other cars, but it's something I struggle a lot with.
"When I take the tablets it probably doesn't make a big difference in the end, but it's something I struggle with so [it's then] easy to make mistakes, so easy to lock up, so easy to spin.
"Valtteri [Bottas had a] spin just in front of me for no reason, or [no reason] that I know of anyway."

Has resurfacing helped with the bumps?
When asked if resurfacing had helped with the bumpiness of the Circuit of the Americas, Norris suggested that improvements could still be made.
"Some bits were less [bumpy], so I'm very happy that they did [resurface]," the McLaren driver added.
"But they resurfaced half of it – that half is a little bit better. [It's] not as good as it needs to be, epecially in these cars.
"I think in last year's cars we wouldn't be complaining, but in this year's cars we complain about everything."
