sleep quality with stimulants?

I just went to look over my old PSG reports, I know they are but one moment in time, and while AHI is greatly improved, the sleep architecture data struck me.

By the time of the second study, I am taking a prescription stimulant (modafinil) morning and noon time, and I notice the data shows huge swing from deep and REM sleep toward light N2 sleep, and I suspect it caused by increased brain activity during sleep hours due to the long half-life of the medicine (12 hours) .
For example, I understand that caffeine, for instance, only has about a 6 hour half life, though it depends on the individual.

I feel more sleep deprived in the last few years than at the time of my diagnosis, even though I am compliant with CPAP therapy.

My Dr isn't sure it the med is affecting sleep, but we agree that the only way to find out is to stop it. ( I should also change mask or do mouth taping).

anybody?

The plan that you and your doctor have sounds reasonable to me. Stop the drug and see what happens. Also fix those leaks, which may be causing repeated arousals that damage your sleep architecture.

Do you know the break-down of your AHI in each of those sleep studies? (The breakdown would be into obstructive apnea, central apnea, and hypopnea.)
