When I was working full time and had to be up at 5:30 AM I would panic if I could not sleep, I could still be awake at 1:00 am and in severe panic mode and crying as I knew without sleep I would not be good the next day. For me, yes, not enough sleep made the next day worse.
I was put on the Ativan 1mg without help and ended up at 4mg at bedtime to sleep. Now that I retired I don't worry about how late I stay up, I take Trazadone 50mg - 150 mg at bedtime for sleep and it really works.
It took a few nights before it kicked in as I did not have much faith in it, but now I do. I am weaning off the Ativan and am down to 1.5 mg.
