WARNING: NOT FOR THE SENSITIVE OR THOSE WHO ARE NOT PROFESSIONALLY TOLERANT. I ve been having trouble with my breathing for about a week or so now; I don t really have trouble drawing the breath, the problem is more that when I breath, even deeply, I do not feel that air has been exchanged satifsfactorily. It s somewhat hard to describe. This issue decreases when I breath through my moth instead of my nose, and decreases when I am outside or if I have fans ventillating my place (but it s still winterish, so I can t leave the fans on all the time). I ve got a form to go get my pulmonary system checked out, but in the meantime, I m wondering as to potential causes. The last times I had this issue, in this same building, were after eating certain foods from a certain chain restaurant, and diphenhydramin hydrochloride would ease them. I ve tried diphenhydramine HCl once during this week or so of troubles, but the effects of the dHCl on my mind were such that I can t recall if it really helped with my breathing or if I just stopped caring off in la-la land. So, searching for anomalous events of late, I came up with that the troubles started after the first time, and may have worsened after the second time of the following: heavy masturbation for probably over an hour, but probably less than two hours, in a closed bathroom with the shower running. The air quality was quite poor as the air was basically steam. The air was saturated with warm vapour and then some. After the first event, I had nearly blacked out. Then again, after the first event, for maybe a day it seemed like I could breath better. The second event (spurred on by the damned dHCl) nearly made me vomit from exhersion, at the end my chest started to really burn, I nearly lost control of my bowels, and I was nauseus for minutes. Could these breathing issues have been caused by these activities?
