I have serious panic attacks to the point I'm in the er. Almost every other day I'm out of my prescription alprazolam I was wondering if I take 12.5 mg of seroquel if I'd be OK never took it before just want to be calm and not panicking and if it is OK for me to take it how lomg does it take to feel it? I do not intend to take this daily or anything like that I just have no benzos at the moment and I can't sleep because of the anxiety I can't even sit still I just pace back and forth I do not want to make another trip to the er I just want to make sure it's OK for me to take
