First off, welcome to the forum!
While many of the longer-term items BP, weight, etc. are difficult, in my opinion to clearly tie to CPAP therapy, one area that is CLEARLY helped is the increased oxygenation of the blood. I think you can agree that having significant O2 in the blood is a good thing. By using a recording pulse oximeter for a number of weeks before being diagnosed with severe sleep apnea, and then for some weeks after starting on an Auto-CPAP machine, I can clearly see the improvement in my O2 saturation date, as shown in the graphs in the link below:

I've been on Auto-CPAP for about 100 days now. My SpO2 is significantly better. I do not feel like superman now. Before CPAP I rarely suffered from daytime sleepiness, or many of the other symptoms usually associated with OSA, other than the snoring and stopping breathing. Some have said I caught it fairly early (I'm 48) and that if I continued, the effects would have been worse over time. My BP is no worse than before, but not better. I have actually GAINED weight (about 6 pounds) since starting CPAP, but I think I've determined that I've been eating more so I'm trying to reduce my diet, as well as exercise more.
But, for me, the improvement in blood oxygenation is enough reason to stick witch CPAP therapy.
Good Luck!
