Club mate is the drink of choice in the start up community in Berlin. I've made the mistake of drinking that in the evening a couple of times and regretted that at 4am by being wide awake and unproductive the next day. If you are not familiar, mate tea which this is based on contains a form of caffeine that is particularly potent. It's like drinking multiple espresso shots. Don't drink this if you have blood pressure…

Is that meant to be Yerba mate auto corrected?

Ok, so it is the yerba mate was correct, but the auto correct not.

Edit, OK I see it is actually yerba mate based soft drink.

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)

The summary on the first page?

I think he/she is asking for a more actionable summary. E.g. consume 10mg of caffeine every 4 hours from 6am till 2pm etc.

exactly :-) Me(he) is asking about actionable TLDR;

> "a form of caffeine that is particularly potent" I've heard this over and over, but as far as I can tell, caffeine = caffeine = caffeine. I'm not a chemist, but I can't find any mention of any different forms -- it's C8H10N4O2. [1] Is there any scientific evidence that alertness is related to anything but the quantity of caffeine, regardless of whether it's delivered as black tea, mate tea, coffee, pills, etc.? Ass…

Yerba mate contains other stimulants as well, like red bull does. So yes caffeine = caffeine, but caffeineted drink!= caffeineted drink.

Surely there’s a better drug than coffee for staying awake for a long time.

Modafinil - https://en.wikipedia.org/wiki/Modafinil

Modafinil scares me. I completely lose time and have little memory of the day - like that movie where the guy fast-forwards his life.

How about, you know, sleeping? Working in a startup isn't being parachuted behind the enemy lines where your life depends on staying alert. Go home, you'll work better tomorrow.

When I was Infantry I used a cocktail of caffeine and nicotine (usually nasal snuff, sometimes supplemented with dipping tobacco) to stay awake on extended missions. Since nicotine is a vasoconstrictor it inhibited night vision to some degree, but that was better than nodding off. Now that I'm a professional engineer and no longer in indentured servitude I stick to an 8 hour work day, get 7-8 hours of sleep a night,…

No nicotine for me, but I would make caffeine "dip" pouches out of the coffee packet and napkins that came with MREs. No one ever drank the coffee, so I always has multiple packets on hand.

Pour the grounds into the napkin to keep it all together, then pop it in like a plug of dip. The taste was brutal, but it got the job done.
