How can I get caffeine out of my system before bed?
We aren’t suggesting you go on a 2-mile run at 10 p.m., but take a light walk around the block (as long as it’s not too late in the evening). Walks can be a good way to wind your mind and body down before bed, and hopefully, it’ll force some of that extra caffeine energy out of your system.

Can caffeine cause anxiety hours later?
Caffeine is a stimulant — and that can be bad news for someone with anxiety. Caffeine’s jittery effects on your body are similar to those of a frightening event. That’s because caffeine stimulates your “fight or flight” response, and studies show that this can make anxiety worse and can even trigger an anxiety attack.
Does coffee not let you sleep?

While it is important to note that caffeine cannot replace sleep, it can temporarily make us feel more alert by blocking sleep-inducing chemicals in the brain and increasing adrenaline production.
