This is my first post so hopefully I dont violate any rules...I am constantly exhausted and even copious amounts of caffeine seem to effect my energy levels very slightly, if any. I have been told that this may be due to adrenal fatigue...is this true? Have any of you heard of this theory before? I am not a hugh coffee drinker, but do take a no-doz every morning and some stout black tea...I also am also prescribed copious amounts of Rx meds from a legit doctor for various maladies, including high BP, bi-polar, GAD, thyroid issues, and CP.. Any advice would be greatly appreciated. TIA!
