At least read the first page of this tiny thread before posting.
like i said earlier, i doubt that any of the passwords i put on the first page are related to this wallet password, and i cant remember any more, so i can't really help you anymore on that front. Best bet is to just bruteforce it.
Even for a million dollars it's not possible to bruteforce your password if it's uppercase/lowercase/numbers and 15 chars long without ANY information about the password contents.
It's not MD5 or SHA, the amount of iterations makes bruteforce extremely slow.
How is it possible to not remember anything about pwd you used? Try hypnosis
