Your opinions on drinking Coke Zero while fasting?

I confess that I have somewhat of a Coke Zero addiction. I've been trying to get it in control.
I've been fasting for 3 months. I've made progress. However, I still drink Coke Zero.
The internet says it's fine but I notice I bloat easily after. I'd like to get your thoughts:

- Do you drink Coke Zero while fasting?
- Do you also experience bloating/flatulence?
- What's your advice on kicking the habit? And sorry, it's not easy to just drink water.
