Hi folks!
I can't believe it - on top of having a marked disc prolapse ( i.e. slipped disc) in my neck causing severe neck and right arm pain & weakness, so I've been off work for 4 weeks (big wake up call on the income front reminding me to work on those passive income streams) - yesterday I tripped getting out of bed & broke my left wrist. As I'm left handed I can't write & can hardly type!
Thankfully I have some info on caffeine that may be useful to you (with great thanks to USANA Health Sciences & copyright to them)....
Take care, I now have doubly enforced rest!

Caffeine improves mood and cognitive abilities
|
At a Glance Study evidence shows that levels of caffeine consumed by most people have largely positive effects on mood, behavior, and cognitive abilities. Read more about this study below. |
The present placebo-controlled, double-blind,
balanced crossover study investigated the short-term cognitive and mood effects
of caffeine in habitual users and habitual non-users of caffeine. Following
overnight caffeine withdrawal, 24 habitual caffeine consumers and 24 habitual
non-consumers received a 150 ml drink containing either 75 or 150 mg of caffeine
or a matching placebo, at intervals of at least 48 hours. Cognitive and mood
assessments were documented at baseline and 30 minutes after the drink.
Assessments included the Cognitive Drug Research computerized test battery, two
serial subtraction tasks, a sentence verification task and subjective visual
analogue mood scales.
At the beginning of the study, there were no differences between the groups' mood and performance. Following caffeine, both groups showed significant improvements in simple reaction time, digit vigilance reaction time, numeric working memory reaction time and sentence verification accuracy. Both groups showed a reduction in self-rated mental fatigue and ratings of alertness. Habitual consumers tended to outperform non-users for rapid visual information processing false alarms and spatial memory accuracy. Separate analyses of each group’s responses to caffeine revealed overlapping but different responses to caffeine. Caffeine tended to benefit consumers' mood more while improving performance more in the non-consumers.
Although, excessive consumption of caffeine, especially in sensitive individuals, can increase anxiety, impair sleep and fine motor control, the evidence clearly shows that levels of caffeine consumed by most people has largely positive effects on mood, behavior, and cognitive abilities.

Pity the Rev3Health/ Energy drink is not available in the UK! It's making massive sales in th US, Canada, Australia & New Zealand - much lower sugar content than competitors & sustained energy! AG
