When I was pregnant with my first and working at an LTC, a resident gave me an old home 'remedy' for morning sickness. She told me forget eating crackers before getting out of bed and all the other things that have been passed down the generations. I had tried every one of the home remedies, wives tails etc to no avail.
Potato chips! Plain potato chips. Worked like a charm
For both pregnancies...as well as all my friends and family who became pregnant after me. Love those potato chips, saved me from morning after morning of wretching
