Yep, I had average to severe, almost hyperemesis the first pregnancy. My OB prescribed some kind of medication, but I ended up forgoing it because I didn't feel comfortable with the possible side effects of it (I had looked them up at the time of prescription). This time my morning sickness is pretty average. I've only vomited once, and if I eat something right after waking, I'm ok for the rest of the day.
I think my morning sickness is attributed to my body "making room" for baby. With my first preg, I was pretty overweight, starting at 152. The first trimester left me so unable to eat that I lost about 20 lbs, but by the end of the preg, I was back up to 152 and baby was born healthy and strong at 6 &1/2 lbs (my family bakes small babies). This time around, I'm not as overweight as I was the first time, coming in at 138, but apparently, it's still too much for my body too handle in addition to a baby. So, as of today, at 7 wks, I'm up to 137. My body knows me better than I do!
