anxiety
"I've found clonidine to be unparalleled at preventing anxiety of the restless and impatient type. I.e. the kind of anxiety that keeps me from sitting in one place. I take clonidine before any engagement where I must sit for a while, e.g., waiting rooms, court rooms and so on. Places where some patience is in order. Clonidine is the best for this. The only side effect is a very slight dry mouth, and that only happens sometimes."
