OK so I just got back from the second stay here to figure out the machine to be used. Alan was here once again to take care of business. He was just as gentle and warm as the first time. I said it before, he is very good at his job. This time I was wired up just like the last time. The difference was I was also connected to the breathing machine. I discovered something about myself tonight that I never considered before. I am a wimp. I did not last the whole session leaving at two am. Now so many folks really find great relief using this device. I found it to be one of the most horrible things I have ever volunteered for. I used the mask that covers the mouth and nose. I felt like I was fighting to breathe, like I was being smothered. It actually panicked me. I am not one to panic. I knew I was not going to be able to continue and certainly not use this each night. So I stopped the session. Alan was very nice and did not make me feel the fool. He gave me the option to take a bit to relax and try again. He also said I am welcome back if ever I feel I can continue on. I just wanted to get out of there and catch my breath, I was belching huge amounts of air on my ride home. This should have been an easy thing to do, Alan sure makes it so. But I just could not take it. So if you ever do this use these folks because they do well and I suspect you will be ok. Oh and one other thing. Something they do not have control over. I believe it is a realty office attached to one side of the building. They have cleaners come in to clean. What they do is make so much noise it sounds like they are tearing the building down. I know it woke the other folks sleeping. I was awake doing my panic thing but if I had been asleep it would have wakened me too.
