Help!

So know it could be worse but Ive never dealt with nausea like this with either of my first two pregnancies. It is just this constant cloud of nausea hanging over me all day but I never throw up. The only time Im not nauseous is if Im starving hungry. Then I eat and I go back to feeling sick the rest of the time. Im a teacher and we start with kids next week. I need something to get me through this. I ordered preggie drops but wondering if you all have any suggestions?? Thank you!!
