Yes, I was diagnosed with sleep apnea earlier this year. They were surprised. They said I did not have the "throat" of a sleep apnea person, I'm thin, non-smoker, no drugs, don't snore, don't sleep with my mouth open etc. They thought it was just narcolepsy but did the 2 sleep studies and said sleep apnea in addition. I have no obstructive, no central, no hypopnea's but had quite a bit RERA's (respiratory effected related arousals).
