Morning sickness has intensified

I think I'm about 9-10 weeks pregnant and my morning sickness gets worse day by day. Now I literally cannot hold anything down. I am throwing up all day and feel so weak. I've tried saltine crackers and ginger ale but it's not working for me anymore. I feel like I'm not able to nourish myself and I'm scared I'm not nourishing the baby. My doc gave me medicine to take but I try not to take it every single day and every 6 hours like she wants me to I only take it when it gets really bad. Is there anything else I can try naturally? I'm so worried and I'm actually scared to eat bec throwing up hurts so bad. I throw up on an empty stomach too but I'm just worried please someone respond
