you know, if you find a good dentist, the process can be not as long. for instance, with my new dentist, i have seen him 3 times: 1 consult, 1 diagnostic assessment, and another consult to discuss treatment. after my 3rd appointment with him, my splint will be ready in 1 week.
all i can suggest to you is to be educated, which it seems that you are, since you're on this forum.
try not to get discouraged.. ive been searching for answers for my TMJD and migraines for over 10 years now. it's only in the last 3-4 years that i've actively taken my treatment into my own hands and have pushed for stuff when most doctors were ready to dismiss me.
anyway, dont get frustrated.. try to be positive - you'll find a great dentist and your symptoms will be alleviated.
