Oh yes! A trip to Chuck E Cheese pretty much guarantees a brief relapse. If I absolutely must go, I always take my cane because I know I'll start staggering. It seems to be worst with multiple noises at once - I can take one loud or annoying noise, but not 3 or 4.

And I startle too! I hadn't heard that from anyone else before. If I'm on the pot and DH suddenly comes into the room and says something, I just about jump out of my skin.
