Caffeine makes me soooooo sleepy, tired, exhausted

And it has a cumu­la­tive effect. UGH. And I wasn’t think­ing about that.
In an effort to be healthy, I bought dark choco­late and have been eat­ing a cou­ple squares a night. I’ve been feel­ing worse and worse every­day. “What’s wrong with me?” I won­dered, “Heart prob­lems? Sick? What the HELL?!?”

Nope, dark choco­late. I had this same thing hap­pen years ago when, in another attempt to be healthy, I drank green tea! Just three cups! One a day! By the third day I felt like I was a sin­gle mother of seven, with three jobs, who’d been run over by a truck. Being HORRIBLY, bone tired SUCKS.

I have reac­tive hypo­glycemia and I already knew that stim­u­lants have this effect on me, but I just wasn’t think­ing about the caf­feine in dark choco­late. I also can’t have herbal stim­u­lants, even seem­ingly benign ones like gin­seng. GR.

I’m not the only one caf­feine has this effect on. Here’s what the inter­net has to say about other rea­sons that caf­feine might make you sleeeeeeepy:

From Give Up Cof­fee:
Caf­feine stim­u­lates the adrenal glands to release adren­a­lin, the ‘flight or fight’ hor­mone that pre­pares the body to react to a threat. It increases your heart and breath­ing rates, dilates the pupils and increases blood flow to the mus­cles. Ide­ally this adren­a­lin release hap­pens very occa­sion­ally dur­ing times of great phys­i­cal stress. How­ever, when we con­sume exces­sive amounts of caf­feine we pro­mote a sus­tained adren­a­lin response, which exhausts the adrenal glands. As a result, these glands are unable to pro­duce even the small amounts of adren­a­lin required to help us main­tain focus and con­cen­tra­tion, which in turn cre­ates feel­ings of phys­i­cal fatigue and malaise.

A sec­ondary effect of caf­feine con­sump­tion that con­tributes to sleepi­ness is that it can dampen the sen­si­tiv­ity of insulin. This hor­mone is involved in detect­ing sugar in the blood­stream and ensur­ing its uptake for energy pro­duc­tion. If insulin is not work­ing prop­erly, we have less sugar avail­able for energy and will feel tired.

Finally, caf­feine con­sump­tion – espe­cially at night – can reduce the amount we get of slow-wave sleep, which we need to be prop­erly rested and reju­ve­nated. A con­sis­tent lack of this deep sleep will def­i­nitely con­tribute to feel­ings of fatigue. Com­bine these three phys­i­cal effects of caf­feine on the body and you have a recipe for fatigue.

Yahoo Answers:

First, caf­feine is a vaso­con­stic­tor (it shrinks your blood ves­sels) thereby, it increases your heart rate and blood pres­sure. This is why caf­feine is so effec­tive for treat­ing headaches.

Sec­ond, caf­feine is also a diuretic (it makes you pee).

There­fore, if you are already dehy­drated, then the caf­feine will not have enough blood vol­ume to shrink down the ves­sels to increase your blood pres­sure, and the caf­feine will increase your dehy­dra­tion to make you more tired.

Tip: this is what I do. Drink at least 3 to 4– 8 ounce glasses of water before drink­ing one cup of cof­fee. You will run to the bath­room in 20 min­utes, but you see that you will have more pep and energy and use the 3 to 4 rule with every cup. You will find that you need less cof­fee to give you more energy

The Caffeine Curve

I get all of this but the good work habits and the ela­tion. No, I do not get a caf­feine high and then a drop. I just get a drop.

    I feel the same way man. It feels like it dehy­drates me or some­thing. I get so tired and out of it!


  • Abz

    you may be on to some­thing :| I feel the same way to!!

    Love your blog by the way, I’m a new visitor/stalker after hav­ing read your inspir­ing mes­sage on another blog which I’ll have to implement:

    *I LOVE just eat­ing accord­ing to my hunger*; only eat­ing when I’m hun­gry and eat­ing what I feel like eat­ing when I’m hun­gry.
    Its SUCH a relief to not obsess about food, to trust my body, and not to overeat.
    I just fig­ure I’ll trust my body and sci­ence can explain later why its so smart. ;)”

    Ahh! Thanks, Abz! It’s good to be reminded of my own good words too.

    I was able to real­ize that cof­fee made me tired even before I read all this infor­ma­tion. I drink cof­fee every day and after the 1st one i feel great for about 2 hours max and than im on the fall till i feel like a total zom­bie worst than i ever had felt to start off with. So I’ll go with out. Whats the point of drink­ing some­thing which will only make you tired in the end.
    Its all about the rush when it comes to cof­fee and even after the 1st the 2nd cof­fee will never feel the same. So i say, no thank you.. Keep the rush and i’ll keep awake . Thanks…


  • wow! i was feel­ing so out of it today and then i reached your space, it was the cof­fee!!! green tea too?? wow! thanks for this arti­cle, much help!


  • restorationgirl

    I am putting down the cof­fee cup as of today. Maybe this is the answer to my ongo­ing Chronic Fatigue that has become debil­i­tat­ing. Green tea puts my lights out. Maybe I’m dehy­drated, too. Never really drank cof­fee until around the time CF started show­ing up & I used to be aller­gic to choco­late (caffiene). I’m going off all caffiene & see if it helps. I’ll give it at least a month just to start get­ting it out of my sys­tem to see if I’m feel­ing bet­ter. Thanks for the encour­age­ment with this arti­cle! Going to drink lots of water start­ing today to flush my system!

    It seems like many get buzzed after the first cup, but later cups can result fatigue. But what if even the first cup makes you tired and you con­sume caffiene rarely? This was my case. Well, I dis­cov­ered I had ADHD and this reac­tion to caf­feine is nor­mal. In fact, my doc­tor rec­om­mended drink­ing green tea to help me go to bed. It seems many adults have ADHD, up to 6% of the adult pop­u­la­tion! 80–90% of cases are undi­ag­nosed! This leads me to think that ADHD could be one of the lead­ing causes of sleepi­ness from caf­feine. Tell me what y’all think.


  • Angela

    After drink­ing one cup of cof­fee I am so tired and so sleepy!


  • Joris

    Stim­u­lants tends to have kind of an ‘oppo­site’ effect on peo­ple with ADHD and ADD.
    I have ADD (after 20 years I finally know), and caf­feine relaxes me. If I take two espresso’s at the same time I start feel­ing relaxed after 20 min­utes or so, and a lit­tle later I feel really lazy, tired, heavy…

    So you may be ADD?
