Valium can make you sleepy, yes. I used to wake up the same way, to the point that it interfered with my relationship. Luckily I have a very supportive spouse. Believe it or not, it came down to being a choose for me. I decided to locate and tackle the demons and to just try to be cordial in the morning despite my mood, even though I was filled with hatred. It slowly became easier to do. That's what worked for me, but everyone is different. I still have my tough mornings but they are fewer and in further in between now. I hope this helps you.
