So I've been having pretty regular morning sickness since beginning of week 6, but on Tuesday it just ratcheted up to a whole new notch. I'm talking 3 seconds warning and puking in front of my superiors at work kind of level. So I called my OB's office and they recommended 25 mg of Unisom (the kind with doxylamine succinate as the active ingredient) at bed time and B6 throughout the day as needed. i gotta tell you ladies, i haven't had a hint of morning sickness (knocking on wood!) since taking Unisom daily. I can't explain how it works, but if you are struggling, please, please call your doctor about it! I felt silly calling about such a normal symptom, especially knowing it wasn't as bad as some women, but I am SOOOOO glad I did!
