After six months of training to hold my breath for long periods of time, my lungs have slowly become more resilient to pain and my body began to use my oxygen more efficiently. I even managed to reach five minutes!

Then the doctor thought that the time has come for me to go further and get to the phase 2 : 5-7 minutes!

I already felt pain in my chest only by imagining having to hold it for so long... But I seated compfortably and let the doctor put that mask on my muzzle anyway as I had no choice.
I then spent another several months trying to slowly reach a seven minutes apnea time. And as always my lungs really hurt, but it is at each time less difficult for my mind to stay conscious as my organism's oxygen consumption is now much more efficient and less greedy.
However month after month and added minute after added minutes the lung fire pain started to become so unbearable that I wanted to scream in the mask even if it would make me swallow water into my lungs, but luckily after some time I managed to reach seven minutes without pannicking... But then the doctor thought that it was then a good idea to add another minute to the timer just to see if I would be able to hold a little longer.
I was furious, my lungs were already on the verge of passing out and now I had to take it even longer?!!! Hell no! I then began to shake, shivers claw the armchair and wiggle my ears as my body began to feel really weird but I tried to remain as calm as possible to not waste the few oxygen left in my body...

Then I felt something special, I started to feel relaxed, very good I would even say, my heart beat frequency lowered, my senses were kind of sleepy, my hearing becoming softer and vision being blurred. And soon my lung pain slowly became tolerable and ignorable, then I reached the eighth minute and got my mask drained.
I caught back my breath in a mighty gasped and then explained to the doctor what I felt during that last minute and asked what happenned...

-"You experienced the second state my son, it is a survival reflex that reduces your body activity in order to consume your oxygen as little as possible, your heart beat slows down, your body temperature gets colder, and your brain turns on a slower pace."

This biological reflex was a good new as I started to feel that things will start to get much better from now on, I was now much less scared to do these trainings in the future, and I was already prepared for phase 3!
