Caffeine addiction/side effects

Beth

So I have been drinking Cuban coffee since I was a little girl maybe like 5? This tends to be a thing with Cubans I don’t know why because a 5 year old shouldn’t be drinking coffee lol. So I’m now 21 years old and I did one of the hardest things for a coffee drinker and switched to decaffeinated coffee. I noticed that I was extremely addicted to the point where I’d get headaches if I didn’t have my coffee every day. Plus it was making my anxiety worse. I made the change to decaf about 3 weeks ago and I’ve only been drinking decaf. I’ve still been experiencing the headaches at times and extreme fatigue. I’m wondering if this is normal and how long does it really take to get over a caffeine addiction. Especially since I’ve been drinking coffee since I was 5.
