Just came across a great free tool called OmniDiskSweeper which is very easy to use. Basically, it outlines exactly what files fo what size you have in what folders on your drive.

I recovered 10 GB without much trouble that I wasn’t even aware I was “wasting”.

Incidentally, on my Mac which has just 2GB of RAM, this tool discovered a 2GB file called sleepimage which I didn’t know I had. Well, it’s what’s used to save all the stuff you have in RAM when the computer goes to sleep. If you lose power, your work will be retrievable through the sleepimage. There’s no point in trashing it as it’ll be remade on the next boot. It can be discarded, however, if you decide to change from sleep mode 3 to the older sleep mode thus saving a lot of space. Read about it here.
