I'm having very hard exam in about 3 weeks. I'm already on nootropics, but I'd also like to add modafinil to improve my memory and concentration even further. As far as I know, modafinil shouldn't be taken for a long period of time because tolerance occurs. But my situation is a bit different because I only need it for one-time event.
So I was thinking to take it last week before exam every single day. Would that be a good idea? What dosage should I use?
What if I would use it only once, just right before exam? Could it actually improve recall of my knowledge?
