I'm terrible in my consumption of phenylalanine artificial sweeteners (ie- Diet Coke is my friend ) But I do quit in pregnancy obviously. Hmmm - I just ate fruit, honey or sugar with DD's pregnancy but I think there is a low calorie sweetener that must be good for you (or not loaded with chemicals) as Dr Sandra Cabot recommends it in her books - it's called 'Stevia' haven't looked for it so can't tell you much more - but I'll keep my eyes open for it and have a read.
