If your doctor is not doing what he needs to do to address these issues you must see a different doctor and make it clear that your sleep disturbances are your reason for seeing them.. For that doctor and that you need appropriate diagnosis/treatment. It is not uncommon to go through several doctors to get diagnosis due to various reasons on their end, but giving up and sticking with a useless doctor is not in your best interests. My sister went through 6 doctors before being diagnosed with PCOS even though her symtoms were clear (to me... She didnt know what it was but I thought pcos and low and behold the 6th doctor diagnosed it with a simple ultrasound that revealed cysts all over her ovaries...)
