When I was pregnant with #2 I got really bad "all day" sickness, DS was 2 at the time, and it got to the point where all I could do was lay on the couch and watch DVD's with him.
It took all my energy to get him food and change his nappy that I couldn't do anything else (plus the throwing up every 10mins or so didn't help my energy levels). I felt so bad, but I couldn't help it.
At 9wks I was put on Maxalon as I had lost 5kgs in just 2wks, after a couple of days on that I started feeling a little better and was able to get by a little easier.
When pregnant with #3, I went on Maxalon at the first sign of morning sickness, so I didn't suffer as bad, and was able to do more with my kids.
