150mg for a double shot of espresso, knock back three before lunch. Boom, I'm at 450mg and it's not really a whole load of volume to drink.
It's easier than you think!

I saved a huge amount of money going from pods to a manual Breville Barista, which whilst making coffee shop quality brew is also far better for the environment. Price of purchase was recovered in 6 months, and all savings from there.
Unless you are pulling two shots of espresso into the same cup (which will likely overflow your average espresso cup) your caffeine intake per shot of espresso is 60 to 75mg. I don’t know of any portafilter basket that would let you get to 150mg in one pull, that would be a quadruple espresso.
I further fell from grace when I started packing as much as possible into a massive percolator for rocket fuel by the filled cup.
But you are right, 3 shots is probably not that much caffeine. It's somewhat hard to get good numbers on it.
If you really, and I mean really want to have a go at the rocket fuel territory, you can do what many cafes in Istanbul now offer: Turkish coffee… at a regular coffee size. I think it takes about 150g of ground coffee per cup. That’s like pulling repeated shots of espresso till you fill a regular mug, except Turkish coffee is finer ground so has more caffeine than your average espresso per gram of coffee in.
Obviously, don’t try this if you have any medical conditions or sensitivity to caffeine, but this is what some Turks often drink on their days off.
https://sleepeducation.org/sleep-caffeine/ Caffeine begins to affect your body very quickly. It reaches a peak level in your blood within 30 to 60 minutes. It has a half-life of 3 to 5 hours.
https://www.ncbi.nlm.nih.gov/books/NBK223808/ The mean half-life of caffeine in plasma of healthy individuals is about 5 hours. However, caffeine's elimination half-life may range between 1.5 and 9.5 hours,
https://www.news-medical.net/health/Caffeine-Pharmacology.as... The half-life of caffeine (time taken for the body to eliminate one-half of the caffeine) varies widely between people, depending on factors such as age, body weight, pregnancy status, medication intake and liver health. In healthy adults, the half-life is approximately 5 to 6 hours. Heavy cigarette smoking can decrease the half-life of caffeine by up to a half and in pregnancy, the half-life may be increased by as much as 15 hours. [...] The stimulatory effects of caffeine may begin as early as 15 minutes after ingesting the drug and last as long as six hours.
