I thought since I couldn't sleep................

Since I couldn't sleep, I thought I'd tell you about my ride yesterday. It wasn't all that long, but it was noteworthy because I rode without supplementary oxygen! I rode a circuit of a bit over a mile without my oxygen on and I didn't experience any chest pain or severe shortness of breath. My heart rate only hit 128, but that's a good cardio burn range. I could tell that I was dropping in oxygen saturation by the time I got home, but the fact is that in March this year; this wouldn't even have been possible! I couldn't even walk 50 feet WITH SUPPLEMENTARY OXYGEN AT THE RATE OF 10 LITERS and more than 50 feet I had to use that wheelchair I've mentioned a few times! I am currently using oxygen at 4 liters daytime and 6 at night along with a BiPAP because I have sleep apnea, not uncommon if you're overweight. Well, that was the high point of yesterday, so I guess I'll try to get some sleep now. Good night all!
