Until I got my apnea treated, I never slept well. I had not had a really good night's sleep in years, and I hadn't had a great night's sleep as an adult probably ever. In school - decades ago - I fell asleep in class regularly and napped every day. Despite this, I have been successful, but I can't help but wonder who I'd be if I hadn't had that problem. What's worse, because you do not actually sleep, whatever happens during sleep that repairs your body doesn't really happen. Sleep apnea massively increases your risk for heart disease, stroke, and many other serious conditions.
Sleep apnea is treated with CPAP - continuous positive airway pressure - from a machine that sits on your bedside. You wear a mask like Bane and it forces air into your throat and opens it, making it easier to breathe. CPAP is not a cure, because it doesn't fix the underlying anatomical issue, but properly calibrated it results in complete remission. I now sleep normally. From a sleep perspective, I feel amazing, better than I have in years. For the first time in my life, I can rely on feeling good in the morning if I get enough hours of sleep in. Even four hours on the CPAP is better than eight or nine hours without it. (Also, over time, your brain becomes conditioned that CPAP = sleep, and you zonk out within minutes of putting it on.)
It is costly and time consuming, yes, and CPAP machines are a huge lifestyle adjustment. But good lord, is it worth it. I have never felt or slept better. In the years since my diagnosis I have not slept a single night without my CPAP and I don't think I ever will again, unless some magical cure comes out.
If you have struggled with insomnia, snoring, or feeling wakeful after sleep, I beg you to get a sleep study and look into whether apnea, or another similar condition, could be the cause.
