I started a cortisol testing this morning. I really have dry mouth in the morning so after 45 minutes I have very little saliva and a lot of foam. I read (which I can't find now) that I can do it the same time tomorrow to add to what I have, as long as I do it at the same time. I also know I can restart but I may run into the same issues of dry mouth. I'm doing 4 a day and if I make a mistake I can rinse the tubes and restart but I'd like to just get this done today. Thanks Please tag me. I'm brainless due to time change.
