Cut out the caffeine. Entirely. Don't think for a minute that it doesn't make things worse. I used to tell myself that it was only bad for the first hour or two after a venti Starbucks or a huge Dr. Pepper, or whatever and that it wore off and then it wouldn't affect me. When I finally cut it out, I realized how wrong I was. My anxiety didn't disappear, but I'll tell you one thing: I don't have to breathe through daily mild to medium panic attacks and what I now know was generalized anxiety. I drink decaf coffee now on occasion and if I forget to say decaf at the coffee shop, which has happened, my thoughts go frickin haywire almost instantly and my chest goes tight and I'm a mess for the rest of the day. I just want anyone out there who's bullshitting themselves like I did, to know that it IS harming you and you WILL be better off without it. I hope I don't come off as preachy. I just want to help. I wish I had learned this lesson many years ago.
