I cant say for sure that i believe in this theory. Since there isnt any science to back it up I will say that I am cautiously optimistic. If this is true then i am kind of happy. I try not to do things that would cause myself the NEED to get rid of stuff inside my body. Should the need arise I dont see why it would hurt to let it come out the other end.
I will share an incident where I had difficulty making it come out. I had apparently caught a little bug during the summer one year, I had nausea off the charts! i even had dizziness. I went to the ER cause I did not think it could be a bug in JUNE! While i was there I had the crazy idea that if i went ahead and did it then i wouldnt have to fight it anymore. I literally had to force myself to V. I gagged and coughed until it finally came. Then, the second episode it came on its own. I didnt have to make it. So maybe there is something to this idea!
