6 months is not a prolonged period of time. ;)

So benefits:

  * mental clarity when unnecessary thoughts go away an only the one you need remains
  * problem solving - look at a problem and solution just pops up
  * stronger mind, doesn't get tired as easily
  * jump in efficiency in everything
  * increased sensitivity to other people's emotions and intentions
  * spiritual growth (realisation that you are not your thoughts is one example, as mentioned below)
  * opening your "heart" and letting go of emotional issues
  * inner peace :)

Important to note that this is from serious meditation practice beyond simple mindfulness and learned in person from a master.
