I used to be a coffee addict in the past. I could easily drink 8-10 latte/cappuccino/mocha in a day. It had a negative impact on me. My anxiety level just got boosted each day and I was in a miserable condition.
Finally, I got rid of coffee and switched to green tea. Initially, you wouldn't like the taste, but you'll get used to it. It has many benefits and helped me in keeping my anxiety and weight in control.
I hope that helps. :)
