I used to take 10mg of Flexeril back when I was in high school for my TMJ and upper back/neck/shoulder pain. I would take it at night, and I would wake up late almost every day. I would feel very "out of it" all day, and I began experiencing feelings of depression. Being a very emotionally stable person, this was strange. I stopped taking it. I just started it up again and took 10mg last night. I woke up somewhat irritable, and I feel extremely stressed and depressed. I feel like crying for no reason. Not sure if I'll continue this drug.
