"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&#039;1 and 98 lbs. at the time."
