A while back I got tested for sleep apnea, had a 6 or a 7 on the scale (mild). I tried the CPAP machine for 6 weeks (inside the time I could return it). My number went down to 1 or something, but, I didn't feel any different, so I gave it up (this was about a year ago, maybe a bit longer).
I decided to try get to the bottom of my tiredness again and was recently at my doctors. He said it would take 3 to 6 months of using the CPAP machine before you'd know whether it would make a difference! I'm trying some other things first (giving up alcohol for 6 months as of yesterday!), taking nasal sprays and a device to stop me snoring.. Really hope something works out as it's just so annoying!
I'm very jealous in a way that the author found out the root cause of their issue. Well done keeping at it! For anyone who has successfully used CPAP, did it really take 3-6 months before you found it made a difference?
