Dose - Caffeine dose for a productive boost, not a jittery fuckabout

[Akewstick]

I've searched, couldn't find anything, sorry if this has been covered.

Stevie Boldank should have been writing an essay for the past 2 days. Thursday he decided he would give himself a break and have a drink with a friend, "a drink" turned into 1.5 litres of 40% vodka between the two of them. Stevie went to sleep at 8am, was woken up by the alarm clock he had set at 11, so he could start work, but was still really drunk and felt like absoloute shit. So Stevie met up with another friend and they smoked an amount of weed he's pretty sure was monstrously large, got home at 8pm, fell asleep at about 10, and slept for faaar too long.

The essay is unstarted, and Stevie is probably a bit fucked, he's on 300mg of caffeine (pills, orally), he's never tried it in any form other than coffee and red bull and all that shit before (and snorting some lines of it when he was 16), so what he'd like to know is this:

How high can you take the dose of caffeine before it ceases to make you productive, and makes you unable to sit down, so you walk around and think about the details that you've noticed in the subject of what makes certain frying pans non-stick, that you never knew existed before. SWIM used to use speed to get work done, and has quite often taken the dosage too high and then discovered that he's on a main road in the dark with his headphones on because he felt the compulsion, and the work he was supposed to be doing hasn't entered his head for hours.

Situation update: Stevie absoloutely ripped through his essay (He prays to god it makes sense, but who can say?) and total intake of caffeine so far is 400mg in about 10 hours, not including 2 pretty large mugs of black coffee, which he reads on wikipedia amounts to 135mg, but these mugs must hold 350ml at least, not 240ml, so prolly more. It's reached that stage (dawn, usually) where you decide "fuckit, any sleep I may get just isn't worth the trouble".

It's 10 to 7am and Stevie is going to visit his family today, and hand in his essay on monday, Lunch around the table with all the children should be interesting, Stevie's been talking to himself all night and lost the ability to form sentences verbally at least an hour ago now. Stevie was sitting on msn with nobody else on for ages untill his friend came on and got bombarded by a torrent of nonsesne from Stevie in the 5 minute window that they were both online.

Stevie is going to keep the pro plus flowing until after the family gathering has toned down, then he's going to crash.

BTW, if you were wondering about dissolving caffeine pills into hot coffee, it's possible, but you need to let it settle so that the filler floats to the top and you can just break it up with the back of a spoon. It's pretty fucking rank, actually. Rank and pointless.
