It's like as long as I'm doing something that I want to do I'm fine . . . wide awake alert focused. The second it's time to learn or read or do work (I'm a legal assistant) I get instantly sleepy literally falling asleep @ my desk. I'm in training with a group at work and OMG I can't even stay awake when the instructor (my boss) is 2 feet away. I'm yawning and nodding off. It's so embarrassing and so annoying and I'm scared I'll get fired. At my old job I was known for falling asleep at my desk. I dont want that to happen again. I used to think it was my sleep apnea but, IT ONLY HAPPENS WHEN I'M BORED OR SUPPOSED TO BE WORKING!. Whats going on?
