I suspect that the normal DST would mean that you're experiencing more activity in the cortisol specific receptors, thus not a lot of suppression from the dexamethasone. That's only a guess.

In fact, why didn't your doctor explain all this to you in the first place? (Answer: just to confirm my opinion that a lot of doctors should really be duct taped to a chair so that someone can explain the facts of life to them. It irritates me beyond belief that so many doctors don't bother to explain tests and test results to patients. Another of my soapboxes.) It may be that your high results were only marginally high, or that your DST results were borderline. That's another thought.

That's the problem, especially with psychiatric difficulties: too many variables to analyse. And it's usually a combination, rather than just one.

Since cortisol needs to rise shortly before you wake up, it could be that eating or drinking artifically sweetened products is whacking out your hormonal systems, thus keeping you up. While it won't be definitive, you could try adjusting your diet to avoid all those nasties for a while and see what happens? Can't hurt, and might help. (Especially since another study regarding the effect of aspartame on depression was halted midway because the negative effects on the study participants were so pronounced. Their depression was so much worse that the researchers halted the study entirely, because they believed it would be unethical to continue it.)

I found that amazing about the study that was halted. I'd never heard about that. I drink a lot of caffeine free diet soda. Here's a link to the study.http://www.mindfully.org/Health/Aspartame-Adverse-Reactions-1993.htm
