Southampton: Jason Roy said low sugar levels caused his dizzy spell in England's first ODI victory over Pakistan (via D/L method) here on Wednesday.
The Surrey star hit a solid 65 as England drew first blood in the five-match series, recovering his poise after seeking medical attention when feeling light-headed.
The 26-year-old was relieved to have avoided any serious problem, saying: "I had to brave dizziness. It was a case of low sugar levels apparently. That's it... Plain and simple.
"I had a headache, felt a bit dizzy... They got the physio and the doctor on, and told me to get some sugar on board. I'll just remember in future on a hot day to be mindful of that.
"Nevertheless, I was able to get my bearings, settle and reset myself and just go again."
England eventually won by 44 runs on the D/L method after two late rain delays interrupted their reply to Pakistan's total of 260 fos six.
When the rain forced an early abandonment, England were well ahead at 194 for three after Joe Root's 61 and an unbeaten 33 from Eoin Morgan.
On his part, captain Morgan wants the one-day team to keep pushing themselves to new heights and believes there is a high amount of confidence in the squad.
"The key phrase is pushing the side. Over the last 12-18 months, we've seen the progression of everyone and the skill levels," Morgan was quoted as saying by a cricket-specific website.
"There's a huge amount of belief. We believe in ourselves. It's almost as though there are no restrictions to anything we can do."
However, Morgan wants more consistency from the side, as the series win against New Zealand, Pakistan (in Dubai) and Sri Lanka have been tempered by losses to Australia and South Africa since the last World Cup, and a climb from their current position of No. 5 in the rankings.
Within the next year, the period which includes the Champions Trophy, Morgan wants England within the top three.
"Realistically, if we want to be favourites going into the Champions Trophy or the World Cup, then we need to work our way up the rankings which means showing more consistency in all three facets.
