Lewis Hamilton is hoping the only high he enjoys this weekend will be that of a British Grand Prix victory.
Hamilton arrived at Silverstone on Thursday plagued by a severe bout of hayfever and dosed up on medication.
The 29-year-old even took a tablet as he fielded questions from the media to alleviate his suffering - and not that being posed by the assembled journalists.
With drug tests now in place in Formula One, Hamilton knows he has to be careful as to what he takes, but has no qualms about that, and instead simply has his heart set on thrilling his legion of fans.
"Everything comes from the doctor and is FIA approved. It has all been checked and it is all okay to take," said Hamilton.
"I remember as a kid I had some severe allergies. I was taking my GCSEs at this time of year and I was sat in the room with a huge box of tissues.
"Everyone else was getting on and doing the exam, and I was just blowing my nose all the time.
"But I have some stuff to get me though. It is non-drowsy. I have tried all sorts of medicines since I was 10-years-old.
"I now have good stuff to help me, but I only take it when I really need it on race days.
"I have not needed it before this year. It's only this weekend at the British GP where the pollen is high.
"With all the stuff I am taking, I should be feeling pretty good. Hopefully I won't be feeling high!
"As for this weekend all I can do is give it my best shot and even if I don't win, I want to make the country proud, but I plan on winning it."
Hamilton knows for him to make any inroads on Mercedes team-mate Nico Rosberg's 29-point advantage in the drivers' standings he has to start pulling out all the stops in qualifying.
Hamilton has made errors during his last two qualifying sessions in Canada and Austria that have cost him dear as Rosberg has taken full advantage of his better grid position.
"The recent mistakes don't play on my mind," said Hamilton, who was almost a quarter of a second quicker than Rosberg in Friday practice, although he suffered an engine failure 30 minutes from the end of the second session that left him stranded on track.
"I have been qualifying for a long time. I have had some great ones and some not-so great ones.
"But I am aware it is very much time for me to start pulling out the very good ones.
"That needs to start this weekend and this is a fresh opportunity for me. I cannot say what is going to happen, but I am going to be giving it my all.
"There is no sense I will not be trying my hardest. I will be doing all I can."
As for the latest technical glitch, Hamilton shrugged it off, adding: "Unfortunately I lost my most important run of the day when I stopped on track. It shouldn't impact the rest of my weekend.
"We will change my programme around (for final practice) to try and recover the time I lost and make sure I can complete my race preparation with a long run.
"It's not ideal, but we'll recover."
