... panic attack is severe and for sleep I'm on halcion .25mg 1 sometimes 2 if I can't sleep. I am also on suboxone for my heroin addition. The klonopins work great but the valum and halcion don't really help. Is there a better med I can take when I get a panic attack and a better med for sleeping? When it comes to sleeping I have tried trazidone, risteral 15mg and 30, ambian. The suboxone is what makes me not sleep so can anyone help me.
