tha'ts exactly the case hello (at least for me)
anecdotally, I've got Hyperemesis and like eveyrone else with that, had real trouble drinking enough for safety - dehydration is dangerous in preg. When I finally began to be able to eat and drink properly, I did have 1/2 beer in sheer celebration. Only it took me 4 hours to drink even half of that half because ,... after a few sips it started to taste wrong.
since then I've had, oh let me see .... 10ml of beer (two teaspoonfuls) about 4 times over about 2 hours, I kid you not. Got a special tiny little 40ml glass for it and all. Week 28 now. Because that's all that tastes nice. Those 2 teaspoons are nice, then it starts to taste wrong ... Just like tonic water, milk, chicken, veggies and everything else.
So ime yes you do stop when it tastes bad. I suppose there's much more of a problem if it tastes consistently good though and you want to drink more than the research seems to suggest is safe.
If people got half as het up about preg women gardening, drinking things with aspartamine or excess sugar in, painting (apparently some of the chemicals in paint can be bad for you?) and caffeine then I could have some semi-respect for the position you can't drink small amounts of alcohol, slowly over some hours. As it is, whatever I personally do or don't drink, i'll stand up against the hysterical unfounded screaming of people who seem to think that one drink will blight your child for life and who interfere with others' views. It's as ignorant as saying that women can't drive cars because it'll damage their womb, a la some Saudi religious people.
Exception: I personally can respect more the people who have had experience of working with FAS or who have actually looked into the data and drawn different conclusions. I can understand the position of people who've worked with FAS, even if I hold a different view.
