Hello you all, sorry about my poor english, but it´s not my main language.
I don´t know if I will say something different, but I had some episodes and would like to share my two cents. I think the episodes were because I was so sleepy during the day due to apnea, that I almost fall asleep. Since I get along with CPAP and start to sleep 6 hour or more*, it didn´t happen anymore.
*Like many others, I had anxiety crisis in this journey (for multiple factors, CPAP use included). When doctor gave me an anxiolytic, it was the first time I could sleep more than 6 hours with cpap.
