How do I know my hypothalamus is working?

Same boat man, always tired, never sleepy. If i have a cup of coffee to wake up, I can expect to stay awake for at least 24 hours. No way around it. Going in for my bloodwork soon. GL to you man, I totally sympathize. Does the seroquel help at all? I've been taking codeine and that usually does the trick for me. The sleep feels natural but I'm still asleep when i wake up.
