I started experimenting with nootropics maybe year ago. There are some interesting effects. I still have to get something that would impress me. Claims that modafinil creates addiction, not true, it seems that same guy is going on forums and spreading those rumors. Anyhow, just wanted to say I am for it, but be reasonable.

However, you should also know, that it is much easier to get a lot of effects just by using things that are easily accesible to us:

* exercise or even walk (like 45 mins)

* coffee (obviously, unfortunately doesn't work for me)

* tea, green tea, yerba mate, others (amazing and powerful effects)

* music - trance or classical work really well

* binaural beats - also work exceptionally well, for focus and for creativity, idea generation

* meditation (goes with the one above)

So what I am trying to say, there are a lot of ways how we can boost our intellects. Let's not forget really enjoyable ones like green tea for example.
