Diphenhydramine
"took 100mg to fall asleep and slept walked in the middle of the night!!! I took a bottle of lotion out of the BATHROOM cabinet, and I must have watered it down and shook it up bc it was liquid the next day and sitting by my REFRIGERATOR!! wtf!! I have no memory of this.. and the next day I was anxious and depressed all over the place emotionally"
