Add 100% isopropyl alcohol or ethyl ether to however much coffee you wish to extract, in a ratio of 50ml/500mg. Caffeine is soluble in most solvents, so as long as you have a non-toxic one that will quickly evaporate (hence the isopropyl or ethyl ether) it should work fine.

Mix the two thoroughly for as long as you can without getting bored. A blnder on the lowest setting works tthe best.

Wait several hours for the coffee grounds to settle to the bottom. You should be left with two layers: One of a dark yellow/brownish liquid, and another of coffee grounds. Allow it to settle until there is no or VERY little particulate matter in the solvent layer, and the coffee grounds on the bottom are fully settled.

Use an eye-dropper to remove the liquid from on top of the grounds. Drop slowly onto a mirror, and allow the solvent time to dissolve. This may take a while, but after the solvent dissolves you will be left with a thin white/yellowish film on the mirror. Using a razor blade, scrape it up to have impure (but at this stage edible) caffeine powder.

To further purify the resulting caffeine powder, re-extract your powder with a different solvent (if you used isopropyl, use ethyl ether and vice versa). After two extractions, you should have about 99% pure caffeine in quantities of up to several grams depending on how much coffee you used.

Alternately, this same extraction can be used on powdered no-doz tablets, black tea, and any other non-toxic plant containing caffeine.

TL;DR: Stimulants help with boring assignments so much it's crazy. Buy some adderall from that twitchy looking guy sitting next to you during a lecture.

Wtf kind of advice is this? He needs to deal with this problem. He needs to find a solution that works for him and do it himself. All we can do is advise him on nonretarded things to do.

If it fixes his behavior, is there really a problem?
