All the same, you can reduce its side effects by staying hydrated, going for a walk, and eating fiber-rich foods.There is some speculation that L-theanine can counteract the jitteriness of caffeine, but this may not be true in everyone.

What does too much caffeine do to your muscles?
Skeletal and muscular systems Caffeine in large amounts may interfere with calcium absorption and metabolism, contributing to bone thinning known as osteoporosis. If you consume too much of this compound, it may also cause your muscles to twitch. Research shows that this level of caffeine intake shouldn’t be detrimental to your heart health, affect your cholesterol levels or heart rhythm. Although drinking coffee has been shown to increase blood pressure, this effect is usually temporary and is minimised over time if you drink caffeinated drinks regularly.Even in moderate amounts it can cause jitteriness and anxiety,” said Dr. Kilgore, noting that caffeine “can also increase respiratory rate, heart rate and blood pressure, which is most often fine in normal people, but if they have a health condition it should be under consideration.How does caffeine affect blood pressure? Caffeine may cause a brief rise in your blood pressure, even if you don’t have high blood pressure. This short-term spike in blood pressure happens mainly in people who don’t drink caffeine often, rather than in those who do.Stimulating your central nervous system (CNS): Caffeine triggers your “fight or flight” stress response, which can increase your heart rate, blood pressure and feelings of restlessness — similar to symptoms of anxiety.If you have ADHD, autism, or other neurodivergent conditions, you might experience what seems like a paradoxical response to caffeine. Many neurodivergent individuals report that caffeine actually calms them down, helps them focus, or even makes them sleepy.
How long until caffeine is fully out of your body?
The levels in your bloodstream peak an hour later and remain there for several hours. About 6 hours after you consume caffeine, half of it is still in your body. Caffeine may not completely clear your bloodstream until after 10 hours. Caffeine’s stimulatory action on dopamine, norepinephrine, serotonin, acetylcholine, glutamate, and GABA neurons is hypothesized to result from its ability to block the action of adenosine, which typically inhibits neuronal function.Most of the stimulant effects of caffeine are from its action on the chemical messenger adenosine. Adenosine is released from nerve cells and binds to specific receptors throughout the body. When this occurs it has a sleep-promoting effect.Because adenosine levels in your brain decrease while you sleep, they are at their lowest immediately after you wake up, Dr Grandner said. So, with little adenosine present for caffeine to block, a cup of coffee first thing will give you less of a boost than when adenosine levels are high.It is an idea that has been popularised by online influencers: Avoid consuming caffeine for 90 to 120 minutes after waking up, they say, and you will perk up more naturally, thwart the dreaded afternoon slump and have better sleep.In order for caffeine to work, the brain first needs to clear receptors of adenosine. This is where a nap comes in to clear the brain of adenosine buildup, allowing caffeine to fit into open receptors. Napping is a brief period of sleep usually taken sometime during the day.
What are two signs that you’ve had too much caffeine?
Signs of Consuming Too Much Caffeine high blood pressure. Some people may feel anxious “Even in moderate amounts it can cause jitteriness and anxiety,” said Dr. Kilgore, noting that caffeine “can also increase respiratory rate, heart rate and blood pressure, which is most often fine in normal people, but if they have a health condition it should be under consideration.Moving your body, whether it’s a brisk walk, some gentle stretching or even a quick yoga flow, can help release that tension and lower adrenaline levels. Exercise also boosts endorphins, which can improve your mood and help you feel more balanced as the caffeine wears off.
What cancels out the effects of caffeine?
Eat the right foods Reach for something rich in fiber, protein or healthy fats—like a banana with peanut butter, a handful of almonds or a slice of whole-grain toast with avocado. These types of foods help slow the absorption of caffeine and stabilize your blood sugar, which can take the edge off that jittery feeling. Eating may slow the release of caffeine into your bloodstream. Opt for slow-digesting, fiber-rich foods, such as whole grains, beans, lentils, starchy vegetables, nuts, and seeds ( 1 ).
How long do caffeine jitters last?
How long do caffeine jitters last? The duration of caffeine jitters can vary depending on your sensitivity to caffeine and the amount you’ve consumed. Typically, the effects of caffeine can last anywhere from 3-5 hours, but some people may feel the impact for up to 12 hours. The timeline for quitting caffeine varies depending on how much you consume daily, how long you’ve been consuming it, and your metabolism. For most people, the worst withdrawal symptoms subside within 7-12 days. Here’s a rough breakdown: First 24 hours: You might feel tired, irritable, or experience a mild headache.Some studies have shown that the incidence of a headache is about 50%, and the incidence of clinically significant distress or functional impairment is 13%. Typically, the onset of symptoms starts 12 to 24 hours after caffeine cessation, peaks at 20–51 hours, and may last up to two to nine days.You can’t flush caffeine out of your system, but drinking water, resting, and breathing exercises can help reduce symptoms. Caffeine overdose symptoms like anxiety, nausea, and heart palpitations usually pass within hours. If you want to cut back for good, taper gradually to avoid caffeine withdrawal symptoms.More than 400 milligrams (about 4 cups) of caffeine is too much.

Can caffeine cause leg cramps?
Caffeine increases body temperature. An overdose of caffeine can cause muscle cramping twitching and involuntary contractions. It also leads to increased urination which can cause dehydration, but it doesn’t sound like you needed to stop for a pee and it probably wouldn’t cause dehydration that quickly. We hypothesize that caffeine may act in synergy with other metabolites, electrolytes, neuronal excitation and inhibition patterns as well as genetic factors to lower an overall threshold for inducing muscle cramps, where none of these factors per se may suffice.
