For nausea, keep crackers by your bedside and eat two or three *before* you get up in the morning. The nausea is caused by your uterus swelling with the baby and pushing on your stomach. That and your hormones running rampant.
I love to knit and crochet and found out that close work like that made me sea sick toward the end of pregnancy. So just do what makes you comfortable.
And have fun! They grow up quickly.
