I wish I had before and after information. Dr. Teitelbaum's office burned to the ground years ago, so my before and after Cortef measurements were lost. I took it for about 2 and a half years and was pretty much normal from it. I weaned off slowly, just in case, but had no problems. This was all prior to, say, 1995, so I don't remember the timing, but my slow deterioration started again at some point after I stopped Cortef, and that has continued steady-on. Valentijn, what do endocrinologists think of saliva tests? What kind of blood workup would I expect if I went that medical route?
