Or the polar opposite: I sometimes wonder if I have a caffeine insensitivity, and whether there's a good way to objectively measure my experience versus the average.
The suspicion comes from how some folks (like in this blog) will talk about how they very clearly perceive being "wired" or having withdrawal symptoms, while I don't think I've ever noticed such clear causation. That includes occasions like switching for a week from/to non-caffeinated sodas. (Diet in both cases for calorie reasons, which conveniently removes sugar rush/crash as a confounding factor.)
It makes for an odd kind of micro-alienation among a workforce where people talk about their needs/habits around caffeine, especially when working near Seattle.
After daily consumption, it takes two to three weeks of zero consumption to restore a sane "baseline" where I can operate at the same level of awakeness with no caffeine. Consuming coffee after the third week has a noticeable impact where you can really feel its effect.
Caffeine doesn't make me more focused; it mostly suppresses my tiredness/sleepiness. Being awake does not equate to being more focused.
I don't think that one week is enough to recover sensitivity if I usually consume daily doses.
Generally, I tend to avoid caffeine due to all the other changes in mood / behaviour / sleep. The effects are mostly obvious if you switch to zero consumption for a few months and then take up the habit again.
Some 10 years ago I tried caffeine tablets in the mornings. They might have been 100 mg. I would take a tablet 30 min before work. That time, it would take the edge off my morning sleepiness which I’ve suffered from my whole life. But instead I would crash completely at 3-4 in the afternoon, so it didn’t feel worth doing.
I use it mostly against anxiety I can get from high caffeine intake.
On the other hand dextroamphetamine works just long enough for an average work day and has much fewer crash symptoms than other common amphetamines. I wouldn't recommend abusing it for work tho, that's a downward spiral IMO.
Perhaps there is an ADHD connection but that desensitization also occurs to those who don't have it. Caffeine is just like any other psychotropic drug, it doesn't take long to develop a tolerance.
BTW, 30mg caffeine is hardly enough to get one off the starting block, a strong cup of coffee can have three to five times that amount.
But yeah, if I drink a Trente anything from Starbucks, there's a whole lot of caffine in there and I feel jittery and uncomfortable, and there's nothing to do about it other than wait and maybe drink extra water and hope that helps.
Well, that shows how large the difference in response to caffeine can be between individuals. Unfortunately, caffeine has very little effect on me, I can drink several cups of espresso coffee last thing at night and it has no apparent effect on my sleep.
I remember when studying using five or more heaped teaspoons of Moccona instant coffee per cup to help stay awake and it was pretty useless even though the coffee was so strong it was just about undrinkable. I also had the same lack of response with super strong brewed coffee.
The writer makes the point that caffeine can trigger migraines and I've also heard this often over the years. This seems somewhat paradoxical because many migraine medications contain caffeine and have done so for a better part of a century. For example ergotamine—the principal migraine medication before sumatriptan became popular—was usually compounded with caffeine and occasionally diphenhydramine in the ratio of 1/100/20mg respectively. So a migraine tablet had the equivalent amount caffeine of a treasonably strong cup of coffee.
Same goes for other headache medications, caffeine is often mixed with paracetamol/acetaminophen in the ratio of 100/500mg or about 100/325mg for aspirin.
I've often wondered why if caffeine promotes migraine then why is it used in migraine medications? The only reason I can think of is that for most people caffeine actually helps relieve their migraine. Presumably, caffeine works synergistically with the main ingredient.
Establishing an appropriate relationship with caffeine is hard! It's hard to have confidence over the right course of action.
The studies seem likely that it is neuro-protective. However it appears to make you stress sensitive, particularly to mental stress. As someone who is prone to mental!/emotional stress but values anything that preserves mental function, what is the appropriate course of action?
I've decided to scale down to the typical healthy dose of 3 cups and see how this impacts me.
But it makes me happy so I see no need to tbh
Anecdotally speaking, whenever I personally go without medication, I am endlessly distracted by even the most basic urges (i.e.: hunger, exhaustion, arousal). Even being slightly peckish would leave me growing increasingly irritated and uncooperative. I've never smoked, but you wouldn't know that by looking at my unmedicated habits -- taking breaks every 20 minutes to satisfy some random urge before I inevitably start losing my head.
And I get headaches in the morning sometimes, coffee + aspirin has been very helpful.
I think it's important for people to recognize this little quirk and not to spiral into a pit of its tasty dark magic.
Good advice. I do this but slightly differently. I drink a lot of tea, I am English after all, but I only drink coffee when I need a boost. I find myself very sensitive to caffeine/coffee despite all the tea.
I aim to have a single coffee a day and resist any temptation to have another in an effort to maintain my caffeine baseline.
