Ask HN: What have been your experiences using Piracetam?

Recently, I have heard and read some interesting things related to the usage of Piracetam as a cognitive enhancer.

It would prove rather useful to have the opinion of other hackers, whose most important asset lies between their ears.

What have been the benefits/side effects you have experienced? Would you recommend taking it, considering the pros and cons of its consumption? In which doses do you ingest it?

All this in order to make an informed decision about taking it, or not.
