6 Signs You're Drinking Too Much Coffee

Are these keeping you awake at night?

I am unashamed to say - I have always loved coffee, and it acts as fuel to get me through my list of tasks. 

However, I began to rely on it heavily, with 2-3 coffees a day.

That was when I realised... I might have been drinking too much coffee

There were some warning signs, like feeling really tired if I didn't drink coffee on holiday, and occasionally not sleeping well at night.  

You're always tired

When you drink too much coffee, you will notice that you don’t have as much energy and focus as you would expect - even after a good night's rest!

If you’re constantly tired, then you might want to try drinking less coffee.

It is possible to slowly wean off coffee by replacing them with alternatives that have either less or no caffeine.

You drink multiple coffees a day

Typically, we start off with one serving of coffee in the morning and that’s it. This will help a lot in bringing you the boost you need.

However, if this habit grows to anything more than 2 cups of coffee per day (just to get that same boost you want), then that cup of coffee may not be doing as much for you as you anticipated.

While caffeine tolerance differs across individuals, experts generally recommend no more than 400mg of caffeine, or 4 servings of coffee a day.

Do note - many cafe lattes already contain 2 shots of espresso each, or 2 servings of coffee!

You can't sleep at night

You may also experience situations when you can’t sleep at night, or reduced sleep quality, such as irregular waking hours, tossing and turning, etc.

That can be problematic, since you will have less time to rest. Sleep is an important time for the body and mind to recover.

This also causes you to feel tired all the time!

When that happens, it may be worth cutting down or replacing your coffee with something more mild, especially in the late afternoons or evenings.

You have stained teeth

Drinking coffee often will end up staining your teeth. It may not be apparent at first, but it can be a problem in the long run.

Stains are caused by buildup of tannins (found in high concentrations in coffee and black teas) on tooth enamel.

Even if you brush your teeth daily, those stains will remain for a while and they will need a professional cleanup from the dentist to get rid of them properly.

To reduce the likelihood of such stains, you may want to cut down on drinking coffee, or if really necessary, drink coffee through a straw.

You get caffeine jitters

Caffeine jitters are a symptom of when you have too much caffeine in your body.

Although some are more sensitive to caffeine than others, the caffeine overload caused by coffee causes side effects know as 'jitters' - but this includes increased heartbeat, restlessness and anxiety.

You get withdrawal symptoms if you don't drink coffee

Coffee does cause addiction - it is the most consumed psychoactive substance in the world! Drinking coffee all the time can cause you to have increased tolerance and dependence.

On the occasion you don't have access to coffee (e.g. on a holiday or a red-eye flight), you could encounter withdrawal symptoms that could range from mild to severe, e.g. discomfort, low energy, anxiety, headaches.

To avoid this, it might be worth considering reducing your coffee intake, or replacing it with something more mild.

What should you do?

I was in a similar situation.

Because of those warning signs, I started searching for an alternative.

I tried a bunch of different things - green or black teas didn't really keep me awake, and supplements like ashwagandha didn't really give me much of a boost.

But later, I discovered Matcha - and it actually lived up to the hype. 

What is Matcha?

Matcha is made from green tea leaves of the Camellia Sinensis plant, ground into a fine powder.

Matcha particles are whisked with hot water to form a suspension with a frothy texture.

Unlike green tea, Matcha (and all the nutrients found in the tea leaves) is directly consumed into the body.

Is Matcha actually better?

While coffee contains approximately twice the amount of caffeine compared to Matcha, the effects of caffeine from Matcha are certainly more beneficial and pleasant due to Matcha's high L-theanine content

There are plenty of real-world, scientific studies about the benefits of Matcha vs Coffee.

Check out the table below for a quick comparison:




Stay sharp longer (4 - 6 hours). No crash.

Get pumped - for 1-2 hours. Then feel sleepy again.


Packed with antioxidants. One of the richest on the planet.

Not much to see here...


Feel calm yet alert - thanks to L-theanine, a natural amino acid that aids concentration.

Jittery, increased heartbeat, jumpy / stressed.


Stronger focus due to the release of serotonin and dopamine

Concentration loss, lethargy after 1-2 hours

Oral Hygiene

Antioxidants prevent bacteria from sticking to teeth, and removes bad breath

Stained teeth, coffee breath

Here's a tip - try swapping coffee for Matcha in the morning for a period of time, and see how you feel. 

It's best to make the adjustment slowly, so you can see how it works for you.
