If you suffer from any kind of anxiety, and you drink caffeine, you should seriously consider quitting. Even if you only drink as little as one coffee per day. There's a very high chance that caffeine is the source of a large part of it.

I've been drinking coffee for 20 years and had always assumed that I was just an anxious, paranoid person. Quitting made me realize that I really wasn't.

Quitting/reducing has also cured my itchy skin problem.

I also highly recommend the subreddit r/decaf as a great source of information.
