Thank-you for all of the informative replies. The sleep specialist typed up a very vague report, but Obstructive Sleep Apnea Syndrome was diagnosed.
I pulled up my health records off of myhealthevet and was able to find the times I complained about my sleep while on active duty:
11/19/15 - INADEQUATE SLEEP HYGIENE
4/12/16 - INSOMNIA - SLEEP DISORDER
9/26/16 - HOME SLEEP TEST, NO SLEEP APNEA, + SNORING
1/3/17 - IN LAB SLEEP STUDY, OBSTRUCTIVE SLEEP APNEA SYNDROME DIAGNOSED, RECOMMENDATIONS: CPAP
I have also talked about my sleep problems with behavioral health and was prescribed ambien 10mg until the day I ETS.
Edit: The first two dates I was still on active duty and the last two dates I had already ets. I thought the outcome would be in my favor but I see the VA will do anything to knock you down.
