Constant Nausea

Hello all! I've had constant nausea starting at six weeks. The only thing that kind of settles my stomach is fruit so I've been eating that non stop. I would rather not take medications if possible but it's starting to really get to me lately. I told the doctor and she prescribed to me Diclegis. From the warning label it says it makes you drowsy and I can't afford that since I have an 8-5 job. Any advice on nausea medications that won't make you drowsy ? Or herbal remedies ? I've tried ginger tea and it doesn't settle well. Pregnancy pops don't help either. 
Thank you for your time!
