If Anita's like me - and she sounds exactly like me - methods of forcing herself awake will not be effective in the long-term. I find it nearly impossible to get up before 11:00 am, regardless of what time I go to bed. I might be able to force myself to get up at a "normal" time for some important event, but it's not sustainable. After two or three days of forcing myself up at 8:00 am, I'll be hallucinating spiders, jumping/screaming at slight noises or movements, feeling like throwing up constantly, feeling weepy, getting huge memory lapses, and pretty much every indicator of extreme sleep deprivation that is characteristic of me - even if I had 8 hours of sleep each night.
I'm not sure if I have hypersomnia, narcolepsy, or some other sleep disorder (just a pathological need for more sleep than the average person). I had an MSLT about 10 years ago that my current sleep doc told me was definitely narcoleptic, but wasn't diagnosed as such at the time because I didn't go into REM sleep at all. However, this was most likely due to the fact that I was taking anti-depressants at the time (which suppress REM sleep). The person who'd analysed the results 10 years ago didn't know that I shouldn't have been on anti-depressants for an MSLT. Anyway, fast-forward to the present, and I have even worse sleep issues than at that time, but I can't do the MSLT because I'm on a lot of drugs that would impact the result and there's no way I can go off them without quitting my job and living a very crappy life (probably house-bound) while tapering off. I did an overnight sleep study recently, but I've been having a lot of problems with night-time insomnia in the last several months, and I only managed to sleep about 6 hours, though I had taken a drug to make me sleep. The sleep doctor said my sleep was short, but what there was of it was completely normal apart from the complete lack of REM sleep (but I'm on more than one drug that suppresses REM sleep).
Besides the extreme sleepiness, I get occasional hypnopompic hallucinations, have severe memory problems (people tell me I've asked the same question three times in the last few minutes, but I have no memory of it; I deposit things in weird locations multiple times a day and then can't find them; I'll take something out of the fridge, put it on the counter, and then go straight back to the fridge and search industriously for it for the next 10 minutes before finding I must have put it on the counter (but have no memory of doing so); I often stop while walking and can't remember what I was doing or where I'm going...etc.), and get something which feels like sleep paralysis when I'm trying to wake up, but I'm not sure if that's what it is (I'll be dreaming with my eyes shut, but I'm awake and really want to get up, but I can't move anything. I might feel that my arm has gone completely numb and want to wake up so I can make sure I haven't permanently destroyed my circulation, but I can't move a muscle, and the dreams keep furiously trying to keep me down. However, it doesn't sound like what I've read about sleep paralysis, in which it seems the person is totally awake - no dreaming - and experiences the paralysis as frightening. Mine didn't feel frightening, it was just annoying. I felt like I had to literally fight the dreams down before they'd let me wake up).
I'm on modafinil now, and it seems to do a pretty good job stopping me napping during the day (as long as I can wake up long enough to take it), but I definitely feel like I'm building a massive sleep debt during the week because I'm not getting in the extra sleep I would normally have during the day. I normally end up having to take a whole day off work per week just to sleep all day to make up for it. Which makes me wonder if I simply have a biologically-programmed need to sleep for a much longer time than most people. With 8 hours sleep, I'm a wreck. 10 hours is doable but not pleasant. 12 hours feels better. 15 feels best of all.
But there is no room in our society for someone who sleeps 15 hours per day. I think I'm pretty much screwed.
