I've had Obstructive Sleep Apnoea OSA for some 8 years since first diagnosis, after diet controls etc I was referred to a consultant who decided straight away that I needed a CPAP machine to keep my airways functioning through out the night. I was 'given' a CPAP machine on HIRE, as in no charge but you are under a 'contract' to have it regularly maintained by the local sleep unit. Boy!!!!! What a difference???? I slept all night about six hours and awoke feeling refreshed and 'rearing ' to go, full of energy. My Sugar levels have come down to single figures, for the most part.
OK, it's strange getting used to wearing a mask in bed but stick at it. You will reap the benefits. The BEST thing ever prescribed for me. I have never looked back.
