How has this pregnancy been different than your first (others)? With DD, I was so sick from 5w3d until the end of the first trimester. I had m/s 24 hours a day and had horrible smell and food aversions. I couldn't go to the grocery store or out to eat, I definitely couldn't cook, and I could only eat about 5 different foods which I had to force down. I only threw up twice, but I was constantly nauseous. I was also extremely exhausted and would go to bed at about 7:30 pm every night.
This time, the m/s pretty much stayed away until the end of 6 weeks. Prior to that, I had a few bouts of queasiness, but nothing too severe or long lasting. From the beginning, most food has been pretty unappealing, but if I start eating something I can usually enjoy it (although this is getting more difficult at times). My m/s is less severe and it comes and goes. I actually have periods of relief throughout the day. When I do feel sick it is gross, but it doesn't last forever. I am also hungry almost constantly, but nothing really appeals to me. My breasts are quite sore, which I don't remember with DD. I'm not as exhausted this time as I was last time, and can make it most nights until 10 pm, although I do usually take a small power nap while I'm laying with DD as she falls asleep. I do have periods of exhaustion in the afternoons when I'm at work.
