Addicted to Soda/Pop?

I'm currently pregnant (21 weeks) and I think I'm addicted to soda! 😩 I can't stop drinking it. I know it's okay in moderation but I feel like I drink way too much. 4-5 cups a day! What can I do to help myself stop??? I think the reason I feel this way is because I quit cigarettes cold turkey when I found out I was pregnant and now soda is like my new thing instead of smoking. If that makes sense.. 🤷 I want a healthy baby. Please help. 🤦
