If you need to know something about patm then i will give you an answer that will most likely help you out and it can be about anything at all. I have very little knowledge about diets and different supplements simply because i am not willing to sacrifice my diet or money trying to find something that might only help me slightly but ive gone a long way in reducing my symptoms.
It happens to me that my own PATM affects me in a way; When in a locked room I start to feel short of breath, I have difficulty breathing, I get dizzy and my head feels heavy. Has it happened to you? Do you know how that decreases without taking it?
Its funny you mention that because just yesterday this exact thing happened to me. How long has this been happening? Because for me it lasted a day but its because i tried something weird. My guess is that you arent breathing in enough oxygen. Patm is a gas and since you are breathing in your own patm im guessing you cant get the oxygen you need. For example instead of getting something like 60% oxygen you get 30% oxygen and 30% patm gas so over time you get light headed and all the symptoms you mentioned.
