Substitute for a former coffee lover?

I used to drink a cup of coffee every day (never more than 1) and recently had to stop because it was too hard on my stomach and kept giving me stomach aches. Even decaf was hurting me... probably just the acidity from it :/

I miss it so much, not even for the caffeine, just for the taste. I feel like I’m craving the taste of coffee all the time and I miss it so badly 😫 I keep trying to get into tea, and it’s just not the same...

Any suggestions? :(
