I went for a sleep study test about 2 years ago and the doctor said that even though at that time I didn't stop breathing during the night, my symptoms of chronic fatigue and gasping for air seemed to point that I have sleep apnea, so he told me to get a cpap machine and I think it's on level six which is kind of on the lower side I think. However.. my sleep/insomnia/chronic fatigue has worsened over the past two years, and I admit, I haven't really used my cpap machine much at all this past year alone, so I went for another sleep study a few weeks ago to see if I really do have sleep apnea (cause I'm thinking a person shouldn't use a cpap machine if they don't need it right?.. maybe it could do some harm? I dunno but I thought I better go back to a different clinic and get a second opinion. I really hope I don't have it because due to my constant allergies I have to wear the full face mask and it feels hard to breathe with it on and makes my skin break out. I will find out on the 21st of April what my results are (I do have all the signs of sleep apnea.. being overweight, my dad and grandpa and two of my uncles have it, I snore wicked loud and I gasp for air sometimes at night and I'm always tired 24/7).. but the only symptom which is a major one for sleep apnea that I don't have is that I can't fall asleep right away.. even when I'm super tired and exhausted. It always takes me at least 3 hours to fall asleep, sometimes I don't sleep at all until the next day, even when I'm so tired and I'm immune to pretty much every sleeping pill. So... I don't know if I have apnea or not, I just want to know if I need to start using my cpap machine again.
Good luck with your apnea, and I'm not sure of what else helps aside from the cpap machine.. hopefully you will be able to adjust to it soon
