Elavil/sleep RYAN 7591

As per my December 3 post, (Atilla) I have started taking Elavil at 25 mg.  I have taken Elavil twice now.  Last night the sedating was not enough to put me to sleep.  Being that I had been taking Antivan for 6 to 8 weeks, is it possible tht the sedating properties of Elavil are lower than Antivan?  I really did like Ativan for sleeping.  It worked pretty good.  My doctor said to start with 25 mg; then I can increase to two Elavils at night.  How many nights at 25mg until you raise the dosage?  Since I couldn't sleep, I did take half of an Ativan; but I will not do this again because I woke up with a panic attack.  Not sure if it was me or the drugs tht caused the panic attack.  I haven't had one of these in quite a while.  Thanks so much.
