I tend to hit around 30 GB per month (pretty much around 1GB per day). Ok yes that's little compared to yours but I am paranoid about hitting the cap despite being on a unlimited service (I just never asked what the limit cap is).
My friend however had it worse than me as he watch alot of HD stuff and is on the pc 24/7.
As for what making me reach that memory sizes, I sometime listen to alot of songs online (I don't download it) and some videoes when I'm bored.
Now I think about it my parent now got into watching live stream channel online which I think they can make around 200 MB or more and that's not including to when my bro, uncle or whoever is sleeping over that are using the net aswell.
