yep, I was like that with my first pregnancy, the only time I didn't feel sick was when I was eating/shortly after. The "little & often" approach was the only one for me!
In my second pregnancy, I was nauseous to the point of not wanting to eat ANYTHING, from 6/7 weeks until 14/15 weeks. I survived mostly on plain baked potatoes, homemade guacamole & weetabix and the very odd small bit of roast dinner, when my DH made me. These were all forced into my stomach because I knew I had to eat. I lost around 25lb over the course of the pregnancy (I was quite overweight to begin with though). I found that having a bottle of lucozade to sip helped in the daytime (I'm shocked I didn't get GD I drank so much of it lol!).
I am not looking forward to the nausea this time (except for the reassurance such symptoms bring!)! Going on previous pregnancies I have about 2 weeks of "normal" eating left!
