Doxylamine
insomnia
"Absolutely horrible experience.  Made me have to go five times during the night.  Could not fall in to deep sleep kept waking up over and over.  Its morning and I am still feeling the effects of it two hours after taking.  Dry mouth and foggy head.  I took 25mg - 1 pill which package recommended for adult.  I will be throwing away the rest of the pills."
