Does it feel like you stop breathing only every once and awhile. not every night, but like if you're thinking about falling asleep. I know what your talking about, when you just about fall asleep and then gasp for air as though i stopped breathing... The truth is for me, that i was thinking/anxious about falling asleep, and when my mind just starts to drift off. I semi-consciously think i stopped breathing and gasp for air. It's all in my head, and possibly yours. If it has only happened since you started panic attacks, it's probably NOT sleep apnea.
