Don't take Excedrin PM.
It has Tyelenol and Aspirin that you don't need.
The PM part in all PM's is generic benadryl.
Just take 1 or two generic benadryl capsules.
My insomnia is under control, but I don't like to take anything for sleep.
You should have done a Plat search. There are several good threads on insomnia.
