Trazodone Hydrochloride and ativan

my doctor just prescribed me with 50 mg of trazodone (once before bed), and 2mg Ativan as needed. I took an Ativan 3 hrs before my Trazodone. 3 hours after trazedone (12am), I went (waddled) to be and had my first good nights sleep in years. The problem was I had slept until 1pm. My husband tried to wake me up, but I guess I was a log. I am taking these for Anxiety/Panic attacks.I don't want to sleep my life away..should I switch to Paxil or something? My headaches are deep and i never get headaches. This is the second time taking them.

I take 150 mg at night, but taking along, it makes me have terrible immobile nightmares. I take 2 mg of Ativan along with it at night to mellow the trazadone out. Both of them together makes me sleep like a log, by itself, I just can't take.
