Stuart Bingham has been supping hot honey and lemon to keep his Crucible challenge on track.
The world number 10 struggled with a cold throughout his first-round match against Robbie Williams, recovering from 5-4 down to win through 10-7.
"I'm still a bit croaky but I went home and I have been looked after," Bingham, 38, told BBC Sport ahead of Friday's second-round game with Graeme Dott.
"I dosed up on honey and lemon and got some sleep and feel OK now."
Bingham knows he will have to be at his best against world number 19 Dott - one of only three players outside the top 16 to make it through to the second round.
"It will be tough," the Essex cueman said. "I will have to be on my 'A game' to stand a chance against Graeme.
"This venue has been very kind to him; he's a former champion  and two-time runner-up and it will be a hard slog of a match.
"The players know how good he is and has rightly been a world champion.
"But I beat him in the UK this season and I didn't play great and that shows how I have progressed in the last few years."
