I did the same thing, except... when I went to clipless I somehow managed to only fall in front of my coach and only in the street. A couple of weeks ago the winds were gusty and I unclipped as we were stopping, then a gust of wind hit the bike and "timber" over I went to the other side. No harm done and off we went again, no injuries except a shredded ego. It's just a matter of practice. But once you go clipless, you'll never go back.
