Take some Modafinil, it's what I take for mild ADD. It's a wonder drug, designed for people with narcolepsy. Keeps you alert, eliminates feelings of tiredness (US Army have been giving it to their troops to give them an advantage, as have French troops in the Foreign Legion, and the UK Ministry of Defence is conducting experiments right now), if you take 600g you will be able to stay awake for 40 hours straight without feeling tired AT ALL. The best part is that you can still sleep whilst on it, if you decide you want to, and if you sleep for 4 hours you'll feel fully refreshed when you wake up as if you had slept for 8.
It has coginitive-enhancing effects too (ie. it increases your brain power), as well as neuroprotective effects, not to mention it's an anti-depressant, reduces smoking/nicotine cravings, reduces appetite, it's been used to treat recovering cocaine and amphetamine addicts.
It has no bad short-term side effects (in trials, the most common side effects people reported were headaches and nausea, but that was only 34% and 11% respectively......and 24% of the people in the trials reported headaches whilst on a placebo, and 3% reported nausea on the placebo)
Long time side effects are of course a possibility, but even though the drug is relatively new on the market it has been tested for over 20 years...and quite frankly the improvement I've felt since taking it is dramatic enough for me to not be worried about side effects.
Parent's Associations and Educational Boards have been having serious discussions regarding this over the last 2 years or so, it's one of their biggest issues - the reason being that many parents are worried about their children being at a disadvantage in exams if they decide not to give them the drug. It's a serious issue as the usage in educational environments is growing massively by the minute - I read a story recently where a University student had been providing it to his fellow students at over £8 a pill here in the UK.....he made over £3,000 profit in a month.
It's a controlled substance in the US, I believe. But here in the UK, it isn't. You can't buy it here though.
So yeah anyway if there was some way you could get that I'd advise it lol....probably a bit late now though.
