My question is not both at the same time for example I was brutally beaten and raped several years ago I am always afraid so because Valium has a longer life time 12hours I can take in the morning.But sometimes I get these horrible panic attacks where I faint I have done it in public places like Ralph's my heart hurts I could take the 1mg Xanax it kicks in faster it spares me being even more embarrassany does anyone do that.Thank You for yor help
