Your right, your pregnancy will drag (at least mine sure have)! And I have been exhausted almost everyday for the last 7 mos. There are days I could crawl into bed and sleep for a wk. It has been real hard for me and my dh thinks I am just being lazy and my dd is no help by getting up at 6 every morning. But on the other hand, I never had one single day of morning sickness(Thank Goodness). So I guess sometimes you just got to take the good with the bad.
Sorry about my little vent. Guess I needed to get that off my chest.
Good Luck and I hope you get your enery back soon!
