Hydroxyzine
"I used to take this medication for panic attacks, and it worked absolute wonders. It took about 30 minutes to kick in but really calmed me down and it wasn't at all addictive. I later found out I have severe hereditary liver problems and it has a bad interaction with what I have to take to keep my liver in check, so I can no longer take it. With the medicines combined I just felt foggy and had to sleep for at least 15 hours if I had to take a vistaril, I couldn't keep my eyes open and function until I'd slept it off.

I'm now trying out Xanax, and I don't really like it, vistaril kept me calm longer and was just amazing when I needed it. With Xanax the half life is just terrible and I end up with a worse panic attack than I began with."
