Carm: the other thing you'll need to try and remember, the bike will "fall" in the direction the tire is turned to, so if you're turning the tire to the side you're still clipped in on, that's the side the bike will fall to. As you stop, try and remember to turn your tire to the "unclipped" side.....that way your unclipped foot will help to offset the lean of the bike. I am with Denise on the leaving just 1 foot clipped, that way you have the power to get the bike going without trying to clip both feet back in.
The thing I did that was a huge help to me, I just rode around the neighbourhood clipping and unclipping without stopping so my feet could learn the routine. That way when I needed to stop, my feet had started to learn what they needed to do. I also tend to unclip on the same side as a rule so it becomes routine. That way in a clutch I don't have think about what foot is unclipped it's already done.
Good on you for not giving up, clipless is the best thing since sliced bread and you'll wonder how you ever rode any other way.
Like a wise woman here told me "you had to learn to crawl before you could walk, same thing with clipless"
As for the road rash, I use triple antibiotic ointment to try and get them to heal as quickly as possible and I use either NewSkin or Nexcare waterproof bandages. Both keep the wound covered and I don't have to keep changing the dressing when I take a shower. After 24-48 hrs depending on how much skin I took off (like my knee right now ) I leave the wound open at night.
Good luck, you can do it....we all went thru the same thing, and let us know how it goes!
