I had same issue and remembered my password after 5 days. I though it was shibeshibeshibe1234 but as it turns out my pass was shibeshibeshibewow1234 . Probably you did something like that.
If you think you can't remember it try mailing :
walletrecoveryservices@gmail.com . A man named Dave is working for bitcoin wallet recovery, I send him information and my wallet.dat but before he cracks it I remembered it .There is also a way that works without sending your wallet.dat, and with that method even if he gets your password he can't get your coins (you can read that further in
http://www.walletrecoveryservices.com/) but he seems like a very nice guy and looks legit so I trusted him.
I made that ruby script work for dogecoin wallet but it's really too slow and i don't recommend it unless you are sure that password you remember is very close to your actual password.
