The 45 day thing, there are exceptions, but I'm blurry on the specifics. I do recall seeing something in the form saying that if you're in an emergency situation, you can request the process be expedited.
I wouldn't worry about it. If you are planning on using suboxone, is there an emergency need to get it faster than 45 days? If not, just sit back and wait.
I can tell you that when I submitted my form, I had some questions, and called the help line. The person on the other end seemed to be on top of helping doctors in emergency situations and asked me if I needed help. She was willing to do what she could to expedite my form, but since it was not an emergency, I told her to save her energy for the docs that really needed it faster.
