Hi All,

I had a sleep study done a while back. The strange part is about an hour and 45 minute period that shows I was awake. They didn't show the mixture of wave types in the report just a graph that plots the stages over time. Well, I can say with certainty that I definitely was not awake during that period. Does this sound like alpha intrusion? The only other thing remarkable about the study was that I didn't have that much stage 3 sleep (less than 10% of sleep time) and there was no stage 4 measured.

About a decade ago I started experiencing some strangeness. Especially early in the night, I am sometimes in a very light sleep. It's so light that I'm sort of teetering on the edge of sleep. It's sometimes sort of a weird dream-like state where it's almost like I'm thinking about something specific or working out a problem of some kind, although there is definitely not any useful thought going on. For example, in this weird state I might be thinking about working on a spreadsheet but the thinking is very repetitive and not going much of anywhere. At times I realize I am "asleep" and in this state. Time can skate by and next thing you know I come to and two or three hours have passed. That's when I usually give up and take a pill.

During the sleep study, though, I was not in this semi-conscious state. I don't recall anything during the period they recorded the alpha waves. Most of the time my main problem is unrefreshing sleep.

Does anyone have any ideas about this? I did find some old posts on this board before where someone described something similar to this but I've never been able to dig much up.

I see my GP on Wed. I am going to try to talk him into prescribing lyrica. Not totally confident I will be successful in this endeavor. I like this doc but if he doesn't start listening I might have to find a new one. Smile

The other weird thing about my sleep that's sort of strange is that I ALWAYS have hypnagogic hallucinations as I am falling asleep. In fact, that's how I know that I'm getting close to falling asleep.

Over the past few years I have suffered from fatigue and many of the symptoms of chronic fatigue syndrome and fibromyalgia. Oddly enough, the better I feel the more trouble I have sleeping. When I'm sicker for weeks or months I'm so exhausted all the time that I have no trouble sleeping, although it's still not refreshing. When I feel somewhat better, like now, I have a lot more energy but need pills a lot to either fall asleep or go back to sleep.

Wondering if anyone else is going through something similar.

No thoughts on this?

I started Lyrica last week. My doctor agreed that it was a worthy experiment. So far it is going well. The first night did not go well. I felt very strange and disconnected. Tired but could not fall asleep and was very groggy the entire next day. But the second night I had no side effects and felt better the next day. The third day was even better. I feel much more normal so far (normal energy, less brain fog, etc).

I'm only taking 75mg at bed time. No plans to take any during the day.

On just this detail:

If they are using the new (2007 in the USA, I think) scoring, there is no stage 4. Used to be stage 3 meant 20 to 50% delta waves and stage 4 meant more than 50%. Under the new system, stage 3 ("deep sleep", "slow wave sleep") is all sleep with more than 20% delta waves and stage 4 doesn't exist.

People need to ask if a system with, or without, a stage 4 is being used.

Similarities to my case. Only I have VERY vivid SPHH, waking and on sleep onset. During my MSLT's I was told that I didn't sleep when I KNOW I did.

What's alpha intrusion?
