Backwards

I am so backwards! For some reason, since I can remember, I've always had a really hard time waking up in the morning and I'm really fatigued all day...since I was a child. I finally start to get energy and feel alive again at around 4 or 5pm! Then I'm wired and wide awake and once bed time falls around I'm not tired and I can't sleep. I have all this energy inside. Before I had Kieran I would take something to help me sleep but now I can't. Even the herbal Skull Cap say's not to take while breastfeeding. So why am I like this? I hate being this way...makes for a difficult day...everyday. When I was 18 I would stay up all night and sleep all day...that worked for me..haha. Can't do that with children though. Is there something wrong with me? I use to think I had chronic fatigue syndrome and saw Dr.s about it when I was younger. If this is fixable, I'd like to fix it. I really wish I I was a morning person...or at least have my energy during the day and be sleepy at night...not the other way around. I mean, right now, I'm ready to go...tons of energy and I think clearer than I did this morning. Is there a way to fix this? Anyone know? I'm sick of being tired all day and being an insomniac all night.
