I have not, unfortunately. I have parents that are self-employed so I don't have insurance, nor do I have the money to afford testing. I've noticed that I have pebbly stool, weird tiny rash on my right arm that cycles on and off, and nighttime awakenings. I've been at this for a couple months and have progressed a LOT on my own without a doctor thanks to forums and a lot of research on the topic. I just can't seem to put the pieces of the puzzle together to fix my sleep. Thanks for the response!
