You can't control the speed of those at OKC but you can ensure that you have provided exactly what they want.
If you Google "FAA" plus your condition you'll find the information you need.
For example, Google "FAA sleep apnea" and the second result is this.
https://www.faa.gov/about/office_or...ices/aam/ame/guide/dec_cons/disease_prot/osa/
On that page you have links to everything you need to determine what tests, data, and information you need to submit to the FAA. Have everything in order and you will, at least, minimize the wait to the extent possible.
