Personally, I might be feeling slightly less tired than I was at end of first tri and the very beginning of second but I'm still exhausted. No second wind here. I have headaches every day in the morning, lastly possibly all day, depending on the severity. I still try to take naps when I can (1-2 20-30 min naps a day while baby sleeps) and I'm STILL worn out by the time 7:30 rolls around. A late night for me is 9pm...like really late. And then I wake up the next morning feeling like I only slept like 5 hours. Maybe 6 on a good night.
