“It’s a level of focus otherwise unheard of, one you can maintain for long periods of time,” said Gutiérrez, a partner in a startup that creates and markets teams of tech talent. (He also runs an online coffee sales business.) “You can crank out code or do some other technical task for hours on end.” I started taking modafinil while getting my MBA at Wharton.

The empty pill capsules could be used for something else, so we’ll put the 500 at$5. Filling 500 capsules with fish and olive oil will be messy and take an hour. Taking them regularly can be added to my habitual morning routine for vitamin D and the lithium experiment, so that is close to free but we’ll call it an hour over the 250 days. Recording mood/productivity is also free a sunk cost as it’s necessary for the other experiments; but recording dual n-back scores is more expensive: each round is ~2 minutes and one wants >=5, so each block will cost >10 minutes, so 18 tests will be >180 minutes or >3 hours. So >5 hours. Total: 5+(>5×7.25)=>415 + (>5 \times 7.25) = >41.

The quadratic y=0.0080795x+−0.000178179x2y = 0.0080795x + -0.000178179x^2 has its maximum around 40mg, though, which seems suspiciously high; it seems that in order to fit the negative estimate for 60mg, the top of the curve gets pulled over to 48mg since it’s almost as big as 15mg. I don’t find that entirely plausible.

I wanted a 500mg magnesium-citrate-only product at <$20 for 120 doses, but I discovered most of the selection for magnesium citrate had sub-500mg doses, involved calcium citrate or other substances like zinc (not necessarily a bad thing, but would confound an experiment), were mostly magnesium oxide rather than citrate, or some still other problem. Ultimately I settled on Solgar’s$13 120x400mg magnesium citrate as acceptable. (To compare with the bulkiness of the LEF vitamin D+l-threonate powder, the Office of Dietary Supplements says magnesium citrate is 16% magnesium, so to get 400mg of magnesium as claimed, would take 2.5g of material, rather than 7g for 200mg; even if l-threonate is absorbed 100% and citrate 50%, the citrate is ahead. The pills turn out to be wider and longer than my 00 pills; if I want to get them into my gel capsules, I have to crush them into fine powder.
