I have a touch overnight sometimes. Better than nausea, which is MUCH less this pregnancy than my other two!!
I had a coworker pregnant with me during my first pregnancy, and she had terrible heart burn her entire first trimester. She kept the fruit tums on her desk and ate them all day! (and, if I remember correctly, she only ate two of the "flavors", so she would have to switch out bottles when she ran out of those colors!)
