Hi All.
I promised I would let you know how I'm progressing with my issue of tiredness, so here it is.
My Doctor arranged an appointment with a lung specialist which I attended yesterday. After checking my general breathing he provided me with a small device that I had to sleep connected to. I had to have a small plastic tube at the entrance to my nose and a sensor on my forefinger, both of which were connected to the machine which was a similar size to a cellphone. I took the machine back to the Specialist this morning and he downloaded the data from it to his PC. So, it turns out that I am suffering from moderate to severe sleep apnea. I saw the graphs on the screen and they showed I was stopping breathing on average 36 times an hour whilst I was sleeping, (only breaths held for longer than 10 seconds were recorded.)
He said that breath holding when asleep is quite common but I was doing it to excess, big style. There is a reliable treatment for the condition which involves using equipment designed to keep airways open, the details of which I won't bore you with, but at least I can now see a light at the end of the tunnel.
....back to vaping:
I said earlier in this thread that the reason I came to this forum is because my wife was sure the tiredness was connected to vaping. I didn't think it was but I thought I would alter the pg/vg ratio just to see what happened; it was 60/40 in my shop bought mix. I'm now using 100% vg (3mg nic) mixed with 10% flavour and it seems to be just fine for me.
So that's it from me. Thanks again for all your help.
Vape on!
