Just curious, you're FEV1 was 44 percent before and it is 44 percent now? Or did it go up to 44 percent after you gained the weight? I'm kind of suprised you were using oxygen if you were at 44 percent before, but I know everyone is different, so maybe I'm missing something.
I think if you added aerobic exercise it would probably help your FEV1. Just my two cents though.
