Erections are all about your body producing the proper amount of nitric oxide in your blood.
Have you ever been tested for sleep apnea OP?
I was and once they hooked me up to the machine and dialed in my proper number I got a huge sleepytime erection like I was 20 years old again and dreamed about pornwhore Lisa Anne's huge titties as said erection's motivator, heh.
I was amazed.
Both at the quality and hardness of my erection as well that I dreamed at all about anything since at the time I basically NEVER dreamed.
Anyway on my home site I posted about sleep apnea and urged my fellow Wizards who were complaining about "brain fog" as well probably "ED" to go and get tested and when the community was well informed enough and continued making threads about their various "problems" I'd ask them if they finally got tested for sleep apnea and pretty much all of them said "yes" and that "it wasn't the problem" but I feel they were bullshitting me and just too lazy to go and get tested.
Yes, the test can be expensive ie $4,000 at times I've heard but hospitals/clinics do have free screenings for it ie free testings for it at times (just pay attention to your local Jewspapers or Jewsnews for ads about this) and or sometimes if you get on certain kinds of NEET insurance or are a high tier wage cuck and have good insurance that highly expensive number to get tested gets wittled on down to practically nothing.
So yeah everyone here experiencing persistent brain fog, ED, candida or various other fucked up issues and mental problems get tested for sleep apnea as it can cause or at least make worse a lot of pre-existing problems that you may have.
