[Treatment] Mild OSA - Not feeling better after 4 months

[PapaColin]

Hello everyone, 

I am a 25 year old male. I was recently diagnosed with sleep apnea after 8+ years of sleeping poorly. My AHI was 6.4, and my REM AHI was 13.1. I'm not overweight. 

I have been using a CPAP for a bit over 4 months now. I am using DreamWear Nasal cushions and pillows, depending on the night (switching settings appropriately). I don't really have trouble falling asleep with the mask, although I still wake up 2x a night to use the restroom. Despite using the CPAP every night since I got it, and having an average treated AHI of 2 or less, I still feel exhausted every day. I was prescribed Modafinil, which does nothing for my sleepiness most of the time. I feel better on CPAP than I do without it but I know the way I am feeling is still far from normal. 

I saw an ENT who confirmed that I have a deviated septum but they said it's unlikely it's causing my daytime tiredness. They performed an endoscopy and said they would not advise a DISE based on their findings. 

I wanted to post my OSCAR data here to see if any of the experts have some insight into why I still feel so tired despite the CPAP saying my therapy should be working. I would greatly appreciate any insight you all could offer, I am really struggling to make it through every day and I am absolutely desperate for answers. Thank you for reading and for helping if you can.

I have attached my OSCAR data from last night. I felt horrible upon waking up this morning and I am exhausted, despite a low AHI.

My sleep apnea is verry bad during my study my AHI was 81 but  now being 15 years older and 40 lbs heavier I
bet it's at least 100.  So I will be on cpap for the rest of my life except if I lose about 150 lbs  but for you  with 
that super low AHI there are a couple of things that just might help you enough so you don't neeed the cpap. 
First for some reason a regular exercise program EVEN IF NO WEIGTH IS LOST ofton helps lower your AHI.  And 
there are some oral exercises that tone the airway muscles that can help lower your AHI.  For someone like me 
while exercise does  help my sleep apnia some and  lets my apap lower my presure I still definitly need my cpap.
So while those oral exercises and a good walking program shure won't let most of us here  they might , just might 
help you enough.
