Actually I thank SatoshiDICE for curing my mild gamble addiction.
Bitcoin gamble is dangerous, because it is easy to access. Much easier than physically attending casino.
Further, there is no such thing as Self Exclusion Request here.
Luckily I met SatoshiDICE and learnt a lesson. The first impression of BTC gamble will now keep me out of it.
Thanks to those who are kind enough to share successful refund experience, now I think I will receive it some time, Although the waiting sucks.

Edit: Finally I've received the refund.
