I did mine after about 10 dives... I was travelling at the time, so I did my AOW about three weeks after my OW.
I'd moved on from the OW site in Malaysia and moved onto Bali, ended up doing a pretty horrific drift dive in a blowing current that was way out of my comfort zone. Away from my tutelage I felt ill prepared and a bit vulnerable that the dive op could put me in that situation, I panicked under there a bit, so decided to 'go back to school'.
I found a great instructor and did my AOW, needless to say the first choice of dives I made was drift! I'd also recommend Peak Performance Bouyancy.
It's a good course done properly and gives you confidence in more aspects beyond Open Water.
