8 weeks along and I don't feel so good

The past week has been hard for me. Morning sickness is lasting all day and the only way to stop the feeling of needing to vomit that's working, is eating. Therefore, I have eaten Shaun out of house and home and have gained a few pounds already. It's weird to feel this way and hard to explain. I'm working on my habits and will be walking on the treadmill for at least 30 minutes a day to get my body in shape. I'm really hoping the sickness doesn't last much longer...
