momotan,
Hmm I think it is quite normal to have no appetite. Cos I checked with some of my frens and myself included, most of us don't really feel like eating, but have to eat for sake of eating. So if you ask me what I wanna eat, I have to think very hard... coz nothing seems appetizing.
I guess it is impt to eat a variety of food, so we don't get sian of 1 kind. For me, I think I sian of fish soup liao.. think I overate it during the initial weeks of preg, I was feel so sick liao, figure eating bland food is good. But now scare of fish soup!! hehe
