Let me start off with congratulations on your 2nd baby;
I have 3 myself, the youngest will be 1 year old tomorrow. I suffered with the nausea throughout each of my pregnancies... morning, noon, night...1st, 2nd, 3 trimester, too! So I can truly say I know how you feel. I tried all the little tricks too, just like you mentioned, but mostly just tried to tough it out, thinking 'Hey, all mamas-2-be go thru this...certainly I can ride it out,too!' Then,to make things worse,my iron was low,so I had to take ferrous along w/my prenatals!Finally,I couldn't take it any longer,and asked my Dr. what secret the other mom's knew that I didn't.'None' came his reply.'Some mom's just get morning sickness,while others do not.' After I made plain the extent of the constant daily nausea I was having to live with,he said the magic word:
You can get it OTC at any drug store.I got to where I just carried the bottle with me,taking small sips when I felt the need. Also,if you're taking your vitamins at a certain time every day, u might try shifting it to a different part of the day,and fill that tummy up good first!
I sure hope this helps you.......Good luck!
