Sleep sleep

I seem to have a major problem with sleep. No no problem with sleeping itself, falling asleep is the easiest thing to do. The problem is too deep a sleep til i can't wake up from it. At first i thought its just me but I found others with this same problem, they seem to attribute it to sleep apnea and narcolepsy. i don't know much about these two disorders, tried reading up on them but couldn't really concentrate.

I managed to get that sleep apnea can cause *MEMORY PROBLEMS* (which BouncingNinjaTurtle certainly knows that i have), high blood pressure, and bla bla bla..so far only one that is applicable to me. Narcolepsy however has symptoms like Temporary paralysis on falling asleep or awakening (i don't know whether i have this), Hallucinations - vivid images or sounds - on falling asleep or awakening (i have very vivid dreams? Maybe these are hallucinations?), Moments (but sometimes extended periods) of trance-like behaviour in which routine activities are continued on "auto-pilot" (not sure about this), and Interruption of night-time sleep by frequent waking periods, marked by quickening of the heart rate, over-alertness, hot flushes, agitation, and an intense craving for sweets (i know i sometimes hunger for food in the middle of the night)

So...
Sigh...
