Hi there Eddie... I expect by now you will have your appointment for a cpap machine. I have been using one for about 6 years now and it has made a tremendous difference to my life.
I was started by the sleep team in St Thomas' Hospital in London on a ResMed S8 machine and after a week of not getting on very well with it, I went back and was given a humidifier to go with it. That made all the difference and I can still remember the incredible feeling of being properly rested and alive when I woke up after about 6 hours of peaceful sleep - it was sensational! Since then I have moved to the South Coast and had my care transferred to the QA hospital in Portsmouth. I have found them to be very helpful and supportive - they've given me a new modern ReaMed machine the S9, which has lots of useful functions like an auto magic pressure monitor which can raise or lower the pressure according to my breathing pattern when I am asleep and has a heated delivery pipe to the facebook that prevents any condensate sloshing around in the tube when the air temperature is lower, such as in the winter months.
As advised, make sure you get a machine that has a water tank, otherwise you will wake up with a sore throat...!
Best of luck.... Robin
