Help with nausea and headaches/dizziness!

Hi ladies, I’m currently pregnant with baby number two and I have horrible headaches and nausea this time around. As soon as I wake up around 6 am until about 10 or 11 am is the worse. My head throbs and I’m occasionally light headed but I just feel so sick. I haven’t vomited or anything yet but only sleeping makes it better, but I work so I can’t nap it off. I try eating toast right away when I get up and that helps on occasion, I drink roughly 8 cups of water every day and I take Tylenol when I can’t handle it anymore but it doesn’t help the nausea as much as it does the headaches. Is there something that you have tried that helps? I’m willing to try almost anything at this point! Only 7 weeks 2 days, so I have a ways to go😣
