Experiences - Modafinil report

[seechao]

Swim has just received 100g of modafinil, he says he ordered it a very very long time ago, and had given up on it, but 5 months latter, he has a lifetime supply. yay.
SWIM had never tried it, and was thinking of using it as an alternative to caffeine, so he weighed out 100mg gelcaps on a mg scale, and tried one out, he informs me that it is more akin to wakefullness than stimulation, he took a second one an hour later, and is still free of gitteryness or tension normaly accompanying caffeine, he feels much more focused, and energised...no, envigorated, like he had a great sleep and whent for a swim. He reports an all arround good/happy feeling, and the urge to sleep he had a few hours ago is gone entirely, SWIM will now go do some homework and see how well it works as a study aid. He is also thinking of takeing another 100mg as it's been well over 45 minutes since his last dose, and it has stopped comming on a while back now, he will wait 15 minutes to be safe, then try another 100mg dose.
SWIM will report later with further developments.
Has anyone else tried it? What kind of dosages are normal, and what are the effects of takeing too much?

UPDATE: SWIM took another 100mg, then another a few hours later, two was nice, three was pleasant but had a bit of a headache/muscle tension, but the fourth made SWIM very tense and jittery, with a headache that had to be treated with painkillers. SWIM's legs where shakey as well. SWIM thinks 2 is good for energy, 3 for staying up all night, anything else seems to have too many unpleasant side effects. SWIM thought for sure he would have trouble sleeping, but he layed down and rested for a few minutes, and slept quite well, woke up feeling refreshed, well, as refreshed as he's ever been after 3 hours of sleep.
SWIM will be giving up caffeine today, switching to 200mg of modafinil in the morning, and a 100mg booster if needed at school, should be easy with this stuff as it works better than caffeine, and he has a whole whack of the stuff
