I guess I'm a little scared because for many many years I've dealt with insomnia. For the last 3 weeks all I want to do is sleep. I've been going to sleep very early. I sleep through the night but when I get to work about an hour or two later, I'm falling asleep at my desk to the point where I can't keep my eyes open. Its very scary. What do you guys think? All of my health test comes back normal all the time. Help me please!
