anxiety
"Clonidine is excellent for performance and social anxiety. But I think its crucial to get the dosage just right for your body weight & metabolism, so that one doesn't get unnecessarily sedated or have dry mouth. I only use clonidine every now & a blue moon  (i.e., rarely), often before a situation or event where I'll need extraordinary patience. I take just 0.1 mg. for this purpose. It prevents nervous tremors of the hand, restlessness and sweating."
