Very angry just after waking up, and unconsciously so

I'm starting to realize that I am VERY pissy and angry and easily irritable just after waking up.

My mother has told me I yell at her whenever she talks to me after I've just woken up, but I literally have had no recollection of it. She would tell me the things I said to her that morning, and I wouldn't be able to believe that I would ever have said those words, or why. And these are some very rude words that are visibly hurting my mother. However, this morning, I remembered saying such hateful and hurtful words, and I want to fix myself.

I want to fix it, but it's like in my half-asleep, half-conscious stupor, I have no rational thought process and no filter to think about what's about to come out of my mouth.

How do I fix this behavior?

Hi,

are you using any sleeping aids/pills by chance?

I am not. Why do you ask?

Ah – I was hoping for an easy solution. Some meds – from my experience ambien and seroquel – can cause you to act *while you are asleep*. Ambien made me sleep-walk, sleep-buy things from Amazon, sleep-email people. Seroquel just leaves me in a haze for the first hour of the morning. But this doesn't apply to you

Sorry not to be more helpful.
