My anxiety is back time to give up the caffiene?

Hi

it has been a long time since I have posted as my life has been good for a while until now. I am 48 yo male recently diagnosed with Angina. I spent an anxious night in hospital after failing to complete a stress test but once on correct medication setlled down to a life of coping with it and doing what the docs ordered. Just before this I gave up on all caffiene that i could identify, ie cola,tea,coffee. This all happened back in March, but around June I started back on the zero coke and normal tea. The fearful feeling of doom descended about 3 weeks ago and today I had a panic attack out of the blue whilst sitting at my office desk. I was alone so thankfully nobody witnessed it. Now after reading how caffiene can prevent ssri drugs working properly and maybe causing anxiety on its own, do you think this is what started my downward spiral?

I knew the risks with caffiene and how certain people can suffer anxiety with it so I guess it is my own fault but sometimes my inner self says go on a little caffiene wil be okay, and a little turns into 4 cups of tea and 3 to 4 cans coke zero doh!

Thanks for reading this and if anyone has similar experiences with caffiene please share so I know it isn't just me.
