I just started using clipless shimano SPD-R's. I just sat on the bike, perched against a wall and practiced for a while till I at least knew the mechanics. I had the tension the lowest it would go. This helped in the beginning, since then Ive tightened them a little. Normally when Im unclipping its to stop at a light so I slow down, not too much, unclip the foot on the side that there is a curb and just let it dangle till I can reach the curb and stop. Takes getting used too, I had my first fall last week, still got the mark to prove it! Hope things work out soon.
