Heart racing & caffeine

Hey ladies! So, I know you aren’t supposed to have much caffeine in pregnancy and I don’t. I actually will be 8 weeks tomorrow and have a total aversion to coffee. I also have HG and have found that sipping on coke throughout the day helps the nausea and vomiting. I’ve looked everywhere for caffeine free and can’t find it; it’s just not a popular demand item.

I don’t know if it’s just because I haven’t been drinking caffeine for months now and so my body isn’t used to it anymore, but even if I only take a few sips, my heart starts racing and I feel funny! Has anyone else experienced this?
