Donating blood

Okay so im up for donating blood wednesday arvo after work.
They really were a big vague on the details of what to expect only that i shud make sure i drink lots of water and eat before i go in...
So who heres given blood and what should i expect.
Can't believe im doing this im scared sh*tless of needles!!
All for the cause i guess
