What is caffeine?
Caffeine is a natural central nervous system stimulant; it's the most consumed psychoactive substance in the world.

How does caffeine work?
Caffeine works by blocking adenosine from binding to its receptors. It works by structurally mimicking the purine molecule adenosine. Caffeine occupies these receptors without activating them, thereby inhibiting the endogenous signal that promotes neuronal suppression.

Why should you take caffeine
Focus: Caffeine makes you more alert and focused; it increases energy and cognitive performance.
Headache relief: Caffeine can relieve headaches by narrowing swollen blood vessels around the brain and also making pain medication work significantly better.
Athletic performance: Caffeine increases adrenaline, decreases the perception of exertion, and increases calcium release in muscle (good to take as a pre-workout).
Appetite suppression: Caffeine can shortly suppress your appetite.

Caffeine dosing
The recommended limit for caffeine is up to 400 mg, though that can vary, and body weight and tolerance; some people can get away with using higher doses of caffeine.

What to take with caffeine
Eat something before taking caffeine: Eating something before caffeine can reduce the energy crash after caffeine
L-theanine: Taking L-theanine with caffeine can reduce the jittery effect of taking caffeine.
Water: Drinking water before and while drinking caffeine is important because caffeine has mild diuretic properties.

Problems with caffeine/potential side effects
Caffeine half-life: Caffeine has a half-life of 4-6 hours, meaning if you consume 200 mg at noon, about 100 mg will remain in your system by 5:00pm. Thiss means if you take caffeine too late, it can drastically worsen your sleep quality.
Side effects:
Anxiety and jitters
Digestive distress
Cardiovascular effects (can raise your blood pressure)

Caffeine tolerance
Your body adapts very fast to caffeine; a big dose can feel very weak after some time. After some time, your body needs higher doses, and you won't see effects from small doses to reset your caffeine tolerance. You need to stop taking caffeine for some time (2-3 weeks) to get rid of the extra adenosine receptors.

Caffeine withdrawal
When you decrease your caffeine intake or even completely stop taking it, your body will get affected with withdrawal symptoms. You can experience headaches, fatigue, mood changes, and increased anxiety.
