I will try to keep this brief. I'm 23M and have been dealing with unrestorative sleep and chronic fatigue/low energy for years. It wasn't until recently that I began to seek medical advice. In recent months, I became aware that my breathing is quite shallow, and that I'm a mouth breather.

I've tried switching to nose breathing and diaphragmatic breathing, but it doesn't feel natural. Is there a way for me to improve my subconscious breathing patterns so that I naturally breathe more deeply? Is this something that can be trained? The goal would be to comfortable nose breathe through the night, which seems very challenging because when I nose breathe now, it feels restricted and like less air is coming in.

I've been away from cubing for years but I am looking for a website I used to enjoy. I remember there was a website that served as an archive of the actual solutions of some solves completed in competition. You could click into a record and see the moves the solver performed. I think I remember the domain name being quite short, and possibly an unusual top-level domain
