I might be the only person that didn't know this at the start of my pregnancy. And so if that is true please ignore me. But I didn't know that potato chips help with morning sickness until I was around 12 weeks pg. I was at the OB office and DH was reading a brochure about m/s and told me that might help.
And so, if you are having terrible "morning" sickness and haven't tried potato chips they might help you as well. I found the plain ruffles were the best. And I would eat them anytime I felt m/s coming on. One night I was going out for a steak dinner and was feeling very ill. 1/2 bag of potato chips later and I felt better and was still able to eat my entire dinner.
That is all. I hope it helps someone.
