Last year i was diagnosed with non functioning, 11 mm pituitary tumor. My biggest problem is unusual sleepiness. I'm scared when driving, I can fall asleep in the shower. I have heavy eyelids, pressure and pain in my nose, behind eyes. I don't have energy, I'm weak and not able to stay awake. I had tons of tests, everything normal. I saw many specialists, everything OK. I was on depression pills(many different kinds), and I feel the same way. What should I do?
