i retrained myself to touch-type when i was 16.

only thing it took was forcing myself to not type any other way, no matter how slow i ended up being. within a month or two i was typing at my previous speed. (and continued to improve from there. these days i type faster than almost anyone who isn't training for competitions)

no tutorials, guides, books, teachers needed. just do it.

ps: yes, those two months are painful. try getting into a heated argument on irc and losing because you can't type fast enough. don't break your touch-typing-only rule. just try hard to type faster the right way! that's where the motivation comes from ;)

I have the same experience, but it took only a week or two to match my two-fingers speed. Talking for hours on IRC helped :)
