Take your prenatals at night, before going to sleep. Sometimes they will upset your stomach, so is way you can sleep through any nausea they may bring. (If they do... I had to be on a prescription prenatal due to some issues I was having, and it was bad for me... But I know plenty of moms who don't have issues with feeling ill from their prenatals at all.)
I had to nibble on a couple saltines (or ritz, when I wanted a better flavor... But the saltines helped more.) while I was still in bed in the morning.
Ginger ale never did much for me, but peppermint (PURE peppermint in e ingredients... not just peppermint flavor.) candies helped!
Also, find something you LIKE the smell of. For me, it was mint, orange peels, and lavender. I made and carried around a little satchel with those things in it, and I would sniff it when my stomach was queasy... Sometimes it helped, sometimes it didn't... But it was a LIFESAVER when a random smell started to set off my stomach. Walking through the grocery store was an absolute nightmare before I learned that little trick!
