drinks drinks and more drinks

omg i’ve cut back on so many things even stopped eating a lot of things. now the only thing i can’t shake is SODA!!! i have to have at least 4 day. that’s not good i know but it’s so hard to kick them to the curb. i’m 35 weeks no GD no PreE. baby is healthy and i’ve actually lost weight instead of gained. i just can’t shake these sodas. and the tonic water is just nasty 🤮 any other suggestions on something can give me a fizz but not as much caffeine?
