I'm 12w3d today and I'm not experiencing morning sickness like I used to. however I commute to and from school 1.5 hours each way! I travel about 2 hours after I wake up, I eat a big breakfast. I pack many, many snacks for my car ride and lunch for the day. I eat about every hour-two hours I found that small snacks help with nausea. but when I'm in the car for 3 hours I just want to cry. my stomach is so nauseous and my mouth waters like I am going to throw up. I car pool, so when I am the driver it's not that bad. when I'm the passenger it's way worse. any one can relate or have any tips to deal with my nausea??! it's driving me nuts and I don't think it will get better with the 2nd trimester.
