I don't know if it really would be that more work if you planned it from the start. Granted, I'm not very good or experienced at presentations and public speaking; so when I do I tend to spend a lot of time preparing. This preparation invariably involves practicing the talk a lot and writing down key words to remind me of points I must not forget. I suspect that writing the talk out at some point during that process would help just as much as (if not more than) spending the same time practicing the talk a few times. I'll certainly try this next time.
