I don't have anything to offer as far as knowledge about cortisol reducers are concerned, have not used them, but I certainly do understand and empathize with your morning anxiety issue b/c I've had it myself, at times very severe as you describe. Very, very frustrating. I've tried a lot of the things you mentioned. Mine mornings are better these days ... not sure why but I think I quit fighting it and have worked more on the concept of acceptance. Oddly enough, it has helped more than anything else.

Whatever you try, I wish you relief. Hopefully someone here will have tried the supplements you are looking into. Believe me though, I do understand. Painful anxiety is a heck of a way to start the day. (((Hugs)))
