Possible adrenal problem - shakings, adrenaline rush, palpitations

Hi guys, wondered if any of you know what it could be. Years ago I made a silly things by drinking loads of coffee and apple juice and exercising straight after. I started shaking, I had palpitations, and my health deteriorated after that somewhat. I wasn't able to drink any caffeine or eat sugar, as I would feel really faint and weird and get palpitations. Now I often feel out of breath, my heart is pounding so hard that it often prevents me from sleeping, I feel uncontrollable shaking and often feel something that reminds of adrenaline rush.

I don't have diabetes or heart problems (checked with a doctor). Could this be adrenaline/cortisol level problem?

Thank you!

I have adrenal gland problems and thyroid problems.  Or perhaps I should say, I had.  Because with the help of medication I'm doing reasonably well. 

The shaking could be caused by a hyper thyroid.  Same with the sleeping problem.  The out of breath reminds me of my adrenal gland issues. 

​I can not drink anything caffeine, or eat anything sugary.  One small piece of chocolate will make my head spin. 

​So yes, it might be both - thyroid needs to be in balance with the adrenals. I would suggest you see a good doctor.

Hi there, thank you very much for your reply! Glad to see that my conjectures might be correct, as I the doctors were being very unhelpful and could never pinpoint what was wrong with me. Which doctor do you need to see, endocrinologist?

For the thyroid I started with my MD.  Then was referred to ... too long ago.  For the adrenals I went to a nature path.
