I agree shinjuku - I worried so much in my first pregnancy and just don't have the energy to this time. I have had tiny amounts of wine on a couple of occasions with a meal (maybe a quarter of a glass) because it forms such a big part of my husband and I dining out (a rare occasion nowadays!) - he loves pairing wine and food, and it felt like a real treat to have a tiny amount to go with my meal.
The same with packaged food. I have been physically unable to cook during the day (luckily inlaws/DH cook at night) as the smell still makes me retch, and the only thing keeping me going has been spending the days out and about, ending up eating boots meal deals etc. The stress of feeling ill while caring for a toddler is enough without worrying myself sick over what I'm eating!
There's so much pressure on women from the moment you get pregnant, and then once you have the baby in terms of parenting - I think it does terrible things for anyone susceptible to any level of anxiety. My lovely midwife last time told me that stress would end up doing more to harm the baby than the things that I was worrying about!
