Morning sickness at night! Help please?

Hey everyone! I am only 6 weeks but the last few days have been getting worse. My morning sickness is really only at night. I can hardly think about food without feel nauseous. I am having my husband pick up some peppermint tea, ginger ale, and saltines now. Anything else help you out? I have to take my prenatals at the last minute before i go to bed or i'll get sick.
