Thread: Almost passed out diuring workout on caffeine

Hi, guys.
I'm addicted to caffeine, consume approximately 750mg per day.
Have anyone heard of people passing out while exercising because of overconsumption of caffeine?
When I stop running on a treadmill, my blood pressure drops and I feel lightheaded. It's like a spacey out of body feeling.

I've found only one study dated 2006.

The caffeine did not affect heart blood flow when the participants were at rest. However, measurements taken immediately after exercise showed a 22% reduction in heart blood flow after they'd taken the caffeine tablets, compared to their previous results. Participants who exercised in a chamber simulating high altitude (15,000 feet) experienced an even greater reduction in blood flow—39% lower.

So if I quit cold turkey, that would fix the feeling that I'm about to pass out?

Thanks!

I’m not sure I’d be going from 750mg/day to zero as that’s likely to cause it’s own issues, albeit temporarily.

Taper down over a week or so and give yourself a few weeks rest
