You're right, Sally. I don't get the bone-crushing fatigue unless I really, really overdo it. I believe the LDN has helped me in this area. Like you, I sleep when I sleep. No rhyme or reason to it. I might be in bed at 7 PM or I might be up till midnight. Just knowing that I can go to bed if I need to helps me not get all worked up about not "keeping" a strict schedule. Not sure what I'd do if I had to work. I'm sure they'd find me passed out on my desk more often than not. Yes, LDN has been a lifesaver for me.
