They say don't drink anything acidic like orange juice

Caffeine and other products that can increase heart rate. I used to be an avid coffee and energy drink drinker, but had to stop after I overdosed one day. After that scare, I greatly slowed down and began noticing I wasn't nearly as jittery and on-edge as before. I now allow myself one energy drink a year and I go for decaf coffee.

Well, I’ve heard caffeine and sugar can give you more anxiety.

Caffine is bad for me atleast. Also thats what my doctor said after the fact.

Energy drinks and alcohol!! I've noticed that Coffee and tea caffeine in low quantities is ok. Alcohol can make you paranoid; which makes sense because alcohol can be an mind altering substance. It really depends on you and how you react.

I quit coffee cause it increased anxeity in me I had my heart pumping and it scared me

Depends on the person. Like Carb heavy foods can give me anxiety,while coffee in general is fine for me
