the mantra my bike shop made me memorize and practise was " sit up, unclip, then apply the brakes." Even so I still sometimes topple over (usually at a stop with loads of people watching, or if I try to turn in too tight a circle. It's always an adventure. Since I have SPD clips and walk around a bit in my shoes, I have also learned to check my clips and shoes for rocks etc. which can catch the shoe and prevent un clipping.
