Sometimes I wonder how big a tragedy it is that many well-written questions are simply dismissed because the author found his solution in the process. I'm sure many of those questions are high quality and would get edits, upvotes and answers had the author just pressed the submit button.
Actually it's acceptable to answer your own question, as long as it's a useful contribution, so it might be worth it to just post the question after all.
Half of the drafts I write do not end up as published questions, just because the writing process itself is often helpful in figuring out what ever problem I have with my code.
