bbjourney,
wat i did is to pre book all friday evening the last time..can book for 2 mths slots..then when i cant go due to menses, i will call 2-3 days earlier to cancel..
they wont scold u cos usually once cancel, the waiting list will take over.. very fast..
but now i have lots of leave to clear, so i can afford to go during day time..weekday he has slots, weeknite , if u wan, gota prebook much much earlier..
i like him, very nice dr..but then too busy until u can hate the waiting time
