caffeine + l-theanine + picamillon. get you going steady. awake or asleep. Sleeping though is in no way replaceable. 8-9 hrs 10-6. Even fact this is mentioned here, is a bit insulting. There should be a study of how many bugs that you produce when awake but sleep deprived with/without caffeine vs well rested( no caffeine after 1pm, no food after 6pm)
Anecdotally, water and sugar directly affect my alertness while using caffeine. If I don't have enough water I get headaches and can't think straight. If my blood sugar is low due to not eating enough, or eating too much sugar and "crashing" then I might as well be asleep, even though I can't from the caffeine. I may have missed it, but I don't see where they account for the diet of their test subjects.
another anecdotal story: I generally skip breakfast and lunch and do most of my eating after work. I find that the longer I fast the more I can focus, provided that I stay hydrated. I do use caffeine (almost exclusively black coffee) for alertness and appetite suppression.
Although I don’t fast I do avoid sugars as much as possible and only drink black coffee or tea.
I drink a lot of tea. About 1 liter a day as a baseline, but if I do some ultrahike or something I can easily drink 3 liters a day. Sometimes for some reason it's really hard to drink my tea (e.g. I'm in a hotel that doesn't have drinkable tea), so I tried to substitute with other caffeine products. Unfortunately I couldn't find out any reliable data on the caffeine content of the tea that I drink. All the informatio…
High- and medium grade green tea (especially the Japanese varieties) have significant amounts of L-theanine, which has its own effects and synergies with caffeine. For me, the same amount of caffeine will have me anxious and give me tunnel-vision if I get it from coffee while more euphoric and peppy if from green tea.

I've been doing this since I was in college ~ 20 years, before the fasting craze became a thing. I just didn't really ever eat breakfast, and now I only eat between the hours of 2 - 8/10ish. I experience the same effects as you described. Increased focus / awareness. Consuming plenty of liquids is definitely required though while you do it.
My goal has been to increase protein intake and reduce my caffeine. My body and brain works better when fueled with protein. With caffeine I have to "refuel" every 30 - 60 minutes and snack on stuff but with a big protein meal I find myself not thinking of food or drink for 3 hours of hard focus.

Yeah, there is a whole subjective component to all of this that is hard to get good information on. I am older, and drink both tea and coffee depending on mood, need for caffeine, etc. There are some online guides that give ratios of caffeine in typical tea versus typical coffee. Of course, figuring out what "typical" is is the issue! What I've seen shows that black tea has quite a bit less caffeine per serving (bag,…
Starbucks drip is absolutely crazy. I always feel awful if I drink on an empty stomach.
Surely there’s a better drug than coffee for staying awake for a long time.
I once spent a boring Sunday afternoon researching the alternatives on Wikipedia. As far as I could find out, they are illegal (Amphetamine), prescription-only (Modafinil) and/or very bad for your health (Methamphetamine). Amphetamine and Methamphetamine are also rather addictive and apparently quitting once you formed a habit is no fun. Ephedrine might be an alternative, but in Germany, it's prescription-only, and I…
I see a lot of Vitamin B6 being advertised for energy, is that all hype?
Caffeine == Caffeine But if a Coke is ~3mg caffeine 100ml and coffee is ~40mg per 100ml, drinking 13.3 "units" of cokes will not be equivalent to 1 "unit" of coffee. 1. Timing of the intake will affect the efficacy (x mg of caffeine over 2 hours vs. 20 minutes is very different to the body) 2. Controlling for time-dependent intake (the spherical human consumed both quantities instantly), concentration of the substanc…
> To use a possibly relatable issue: most people find consuming shots of vodka more efficacious than consuming the equivalent amount of beer by alcohol. 3 shots will probably get you more wasted than necking 3 beers But it won't, after drinking 3 beers after each other your BAC will go to the same level, just takes a little more time to get there. Subjectively, you start feeling drunk much more quickly because the ch…
This is not true and is the nature of the discussion. Alcohol and caffeine are processed differently depending on what they are consumed with, like how the digestive cofactors in apples make it have a lower glycemic index than it's fructose content should produce.
To stay with alcohol, this is easily testable. Drink five shots of vodka and see how drunk it gets you. Separately, drink five shots of vodka with honey added and you will get significantly drunker. Your liver prioritizes sugars first, so the alcohol is rapidly absorbed and takes effect instead of being processed out. You do not reach the same BAC in each case, just like drinking 5 shots in five days won't either.
In case anyone found that study difficult to read, the optimal strategy was, over the course of 3 days, one 600mg dose after 12pm on days 2 and 3 of a 3 day string of sleep loss.
Well, that works if you know you are going to have to deal with poor sleep for three days in a row.
Sadly, my sleeping problems don't have clear external factors like that so I usually don't know if I'm going to have three days of bad sleep ahead of time like that.
