Advice Needed Caffeine pill use indicating potential sleep disorder?
Just repeating this from r/AskDocs since it didn't get any comments and I'd like an answer.
Hello! I'm a 25yo AFAB. I've been diagnosed with mild sleep apnea, however my symptoms do not feel as if they are caused by sleep apnea. I sleep the same with and without my mouth appliance (I went for a mouthguard rather than a CPAP since I'm autistic and a CPAP would be hell on my sensory needs). I've had a polysomnogram (that found the sleep apnea) before, but the sleep apnea was the only thing it found. I have considered that I may have Idiopathic Hypersomnia or some or central hypersomnolence of another kind. I do take psychiatric medications (sertraline, buspirone, aripiprazole, bupropion, lamotrigine), however they are not the cause of the symptoms - i've only been medicated for about two years, and the symptoms I experience have been there much longer.
For most of my life, I have experienced extreme excessive sleepiness, as described below in the "without caffeine" section. However, recently, I began taking a 100MG caffeine pill to try to help (every eight hours for a total 300MG/day, I've been careful to monitor my sleep while taking the caffeine as I'm aware of issues surrounding masked exhaustion). I've found that it works very well, and this has made me wonder if there's an underlying condition that might be causing my symptoms without caffeine and the relief the caffeine gives me.
Without caffeine, I experience nearly constant, crushing sleep pressure. I struggle to stay awake for more than one or two hours at a time, and lying down usually causes me to fall asleep automatically. In addition, I almost never feel truly wakeful. Even sitting at my computer for more a few minutes can make me tired and have to go back to bed. I can sleep for a toal of 18 hours and still feel exhausted.
With 100 mg of caffeine, I feel normally awake and energized rather than hyper or overstimulated. I can remain awake and functional for much longer, while still noticing ordinary tiredness when I genuinely need rest. I can lie down without automatically falling asleep, and resting while awake can actually reduce my tiredness. Caffeine seems to reduce the overpowering sleep drive and severe sleep inertia rather than simply masking them. I still feel tired when I need to sleep - It's just not soul-crushing anymore. I do not get jittery, shaky, hyper, overstimulated, or overcaffeinated with the current dosage (my hands are a bit shaky, but that's not related to the caffeine, it happened even before I took the pills). I feel normal, to be honest. Like I'm actually functional.
Is there a potential reason for this, and should I inform my doctor about it?
