I've noticed since low carbing that I don't seem to need the same amount of sleep as before. Before diagnosis I could sleep 24/7 if I wanted to, I was tired all the time to the point of slothness. Once I started on meds and changed my diet, I became more alert and the foggy brain all but disappeared. I found myself staying awake longer, don't get that afternoon slump after lunch, go to bed at 12 and am awake before 6 most days and once I'm awake I can't get back to sleep. Occasionally, I'll have bouts where I wake at 4 or 5 which annoys me because I can't get back to sleep unless I read until my eyes are sore.
I try to go to bed by 12 and don't drink for at least 2 hours before bedtime and have my kindle on hand full of boring books for when I wake up. :roll:
