Been there, done that...more often than I care to admit. And actually, there is a way to search for all your posts, or all of anybody elses. (Well, at least the most recent 999 of them). Just put your cursor on your name at the top of any post and click. A drop down menu will show up that has the option to "find all posts by XXXX." I know this because of the number of times I've had to use this feature to find my own "last post" on these monthly threads so that I could copy and paste my weights.
