Re: sigh, I don't know how much more I can handle...
The exhaustion you describe sounds exactly like the anemia I have dealt with in each pregnancy. Try some iron supplements. For me, it's like night and day the difference. If you aren't anemic, the iron supplements aren't going to hurt anything, but if you are, they can really help. If you are prone to constipation you will want to try some stool softeners tool. Both have been prescribed by my doc with each pregnancy. Well, I say prescribed, but it was actually OTC stuff, just a generic CVS iron supplement and some phillips softeners.
