Has anyone had problems with sleeping on this WOE. I haven't had much sleep in the past week or so. My husband had a cold, and you know how men are when they are sick. Anyway, I should be really tired by now, but in the last 3 days I have worked 8-9 hour shifts, went for walks, and only been able to sleep 3 hours max. I am tired, but cannot sleep.......I have meds for anxiety but don't want to take them unless absolutely necessary..... any ideas?
