Lorazepam
"If you're using this drug for anxiety make sure you read up on it before you use it for more then an occasional anxiety-fix.  Even at the minimal dosage, using this stuff daily for even a week will cause problems.  Namely - it CAUSES anxiety.  From what I've read this is a dependence that develops - either (or both) physical or mental. After only a few times you get accustomed to it "fixing" your situation.  Your body adjusts for the GABA boost, and then "crashes" - resulting in anxiety.  Very bad loop to get in.  Warning signs: you're counting the # hours the med will still be working (about 6 total), you're watching the clock for when you might be able to take another pill, you always carry a pill in your pocket, etc. Those are bad signs."
