From Insomnia to Narcolepsy??

I have always been an insomniac since my nursing student days. It got worse during seminary days and the thinking process that goes into Bible translation can make the wheels of your mind turning and churning deep into the night so having 4-5hour sleep most days is good and normal. Therefore when suddenly you start sleeping like the dead, unable to get awaken by sounds of lawn mowers or chainsaw right outside your window or people almost yelling at you trying to wake you up, and bones and muscles that seem to lose their strength for no reason, catching yourself napping in the middle of the day when for years and years you haven't been able to, a headache that never seem to stop, dizziness that is so severe you feel like your world is just a top being spun over and over, it could absolutely scare the daylights out of you. 

So to the doctor I go hoping to get clarity on all these symptoms and I aside from the usual culprit that is stress and anxiety, with my lowest blood pressure reading have consistently at 140/95, and usually spiked 4-5 points above that, he suspected that I may have suffered what they call a silent stroke, and that the excessive sleeping, the weakness in my bones and muscles may be a way of the brain to heal itself. So he said he needs to get a peek into my brain with a CT scan and an MRI, to confirm, or to rule out. He also did say that if my life has become so much more stressful, my old migraines and tension headaches might just be reacting. I hope it is the latter.  

So we'll see.
