Similar Problem to woodbldr
My problems are very similar. Once I go for the a (especially the second) breath, I lose all focus and struggle. In addition, I have a difficult time regaining my breath and experience extreme bloating. I'm beginning to wonder if I'm allergic to chlorine or some other chemical in the water. I am a very good athlete and am indeed frustrated with my lack of progress when I see so many others "get it". Any thoughts?
