This is a reply to everyone in one post.
Thanks for the suggestions. Unfortunatley this is a very ingrained problem, and I've already done everything suggested. Sometimes a good Liver Flush
helps the oxygen for only a very short time, but then I would backslide again.
Flushes unfortunately have not worked out, and I did a ton of them.
Tried ozone water, meh I felt something but not much.
Antioxidants, same, meh, felt something but it's not helping enough to invest time in.
The only thing that helps is being in very fresh air, and it only helps a somewhat it won't fix the problem.
Sometimes after expelling large worms then I feel like I can breathe but it's a short-lived relief.
The problem seems centered in the colon, but that's just a guess.
Looks like my best option is just to keep doing parasite
cleansing. I also have a chronic dry cough so there are multiple causes going on.
