I'm desperate for some advice! I suffer from severe/extreme fatigue and can't seem to determine the cause. I've done the sleep study (no sleep apnea), i've had my thyroid checked (normal), i've had a complete physical (everything "normal") and yet I have struggled with fatigue for about 20 yrs!!! It has gotten worse over the years - I have trouble waking myself up (similar to sleep paralysis, but no hallucinations), if i'm feeling tired but continue to push myself, it takes me 1-2 days of constant rest to get back to a "functioning" level of energy, and i've recently had dreams that I am so tired that if I let myself go into as deep of a sleep as I feel I want to that I won't be able to wake up again. I usually wake up from those dreams feeling like dead weight/drugged. Whether I sleep 6 hrs a night or 12 hrs a night, I still feel exhausted......
