anxiety
"I was prescribed this when I went to a 5 day inpatient detox. They gave me this for anxiety as I could not use any benzos, due to my addiction. So when I left detox I remained on clonidine for about 5 months. It did significantly relax me, however, it lowered my blood pressure so bad that I would get  a head rush and faint almost everytime I stood up. Keep in mind my size definitely was a factor as I am only 5'1 and 98 lbs. At the time."
