You should get 24 hour saliva testing done so you know when and whether your cortisol is high or low, both can have similar symptoms but hugely different treatments. It takes a long time to recover from this so try to hang in there. If your BP isn't sky high keep up with the salt I found it a huge help I dose 3 times a day with 1/4 tspn.I find it amazing that you have been put on Hydro,DHEA and not been tested!! Adrenal fatique isn't just localized to the aderenals it impacts on other areas as well especially the hormonal system, digestive as well, so it can take a while for all things to come back on line, I would stay off all gluten and Sugar as well, eat plenty of fibre to keep regular and don't forget water!!
