Works fantastic for panic for me and often it will eliminate the anxiety symptoms altogether. It solves an emergency hyperventilation response to panic, it does take about 25 min and you might feel drowsy before the effects kick in. I am always tired after taking it, if you hardly take it, 1 mg makes me feel like rubber and very..different and very drowsy. That was overkill really, .25 to .5 is enough to kill a panic usually. Always try to walk around and see if the panic subsides in about 30 mins, if it doesn't then I take the pill. Sometimes people over medicate, remember that your pill takes time to kick in, enough time for some panic attacks to move on without even taking anything.
