When I first brought home my Avail Inspire, all fitted at my LBS, I had such issues with falling and feeling insecure with stopping with the clipless pedal. Part of the problem was the first few times in trying to get on my bike the "right way" I snagged the chamois of my shorts on the seat and quickly became off balance. I did get to a point where once I was going I was fine, but i truly feared stopping, because that meant starting again. Finally, I lowered my seat barely 1/4 of an inch, maybe even closer to 1/8. Small change, big difference. From there I could start with one foot locked in and my butt on my seat. I do not use my feet to stop, but I do unclip, slow to almost a stop with my unclipped leg out and let it catch the ground when the bike has almost stopped with the front wheel turned slightly the opposite direction. Then I unclip the other foot, get it to the ground and come off the seat with both feet firmly on the ground. Not exactly proper, but it works for me and it sounds a bit higher than where you are at.
