Unfortunately, what you are describing still sounds like motion sickness. Dramamine is not effective for all patients, but be sure you are not using the non-drowsy Dramamine, as it does not work either. Also, you may want to confirm with your vet that you are using an appropriate dose. Give it to your dog a good 1-2 hours before you get in the car. If it is not enough, your vet can prescribe a drug called chlorpromazine, which is often effective with more severe motion sickness. Unfortunately, even if you can control the symptoms, she will always find it challenging to be a riding-around dog partner because all these drugs will sedate her.

Always remember that if your pup gets sick, take a step or two back in the process until more tolerance in the car is built up. Stay calm and remember that sometimes dogs show signs of anxiety through whining, drooling, vomiting, or licking their lips. Keep your cool and try the next day again.
