Hello everyone! I'm new here so I apologize if this is a repeated topic. I tried skimming through the posts but didn't see much.
My situation is that 1-2 days a week I have a much harder time than usual getting out of bed. I was diagnosed with narcolepsy a couple weeks ago. I always have a hard time getting out of bed and getting to work on time but there is always a couple days that I can't get out of bed at all. Its a different feeling than normal exhaustion. When I wake up I feel like my entire body is made out of lead. I can move, but barely. If I get up my head is so heavy I have to lay back down. This feeling lasts all day. So I end up skipping work and sleeping the day away. I have to push so hard just to get up at 5:30pm when my boyfriend gets home. It almost reminds me of sleep paralysis but the difference is I can move, its just very hard, and it last at least 8 hours. I'm very lucky that I still have my job at this point but if it continues I can't imagine I will much longer. 
I was wondering if anyone else has experienced this and if so is there anything that can be done? I have a few more weeks before I see my doctor again so I'll be sure to ask him when I see him but until then just wondering what your thoughts were. 
Hello Melanie:
I used to have something like this feeling, except it would suddenly (and randomly) occur during the day. I would suddenly feel as if I had weights tied to all my appendages and my head was heavy, too. I was working in the theatre at the time, and I can assure you, suddenly feeling wiped-out, off-balance, AND heavy while on a 40 ft. ladder holding up a light fixture is NOT fun!
I did a neuro transmitter test with my doctor. They aren't considered accurate (there's not a great baseline for them yet, and the blood/brain barrier also causes an issue with it) but it did me a HUGE favor: it identified a major imbalance. Dietary.
As sleepy people -- and narcoleptics especially -- we're often pushed to keep alert, keep awake. I'm not complaining about this at all, but the fact is, our brains and bodies like balance an equalibrium. And if we push too hard against that, the brain / body may backfire.
In my particular case, there was an incredibly low GABA count. GABA is involved in sleeping (among other things) and is an inhibitory neurotransmitter. ALL of my excitatory neurotrasmitters (like nonepinephrine) were elevated, but my GABA was very, VERY low. This is bad because GABA is suppose to "GO" when excitatory neuortransmitters are out and about...!
The reason my GABA was low was also revealed in the test: my Taurine levels were very low. I hadn't been eating many meat/fish/other products with taurine, and since Taurine is majorly necessary for GABA production, my GABA was incredibly low. Especially for someone taking amphetamines!
So even though GABA is an inhibitory neurotransmitter, low levels caused me to feel heavy, wiped-out, and, well, lackluster is the only real word for it. I had no pep, no energy, AND -- I had a hard time even sleeping... which makes sense, since GABA helps during sleep.
I took a Taurine suppliment (1000mg/day) and started to change my diet. Once my diet was up and running with better nutrients, I dropped to 500mg/day, then got rid of it all together. The heaviness/lackluster/wiped out feeling went away. The first week it still happened, but it happened less frequently (and less severely) by the end of the week for me. All I had to do was make sure I was eating better -- in my particular case, fish and beef, which I had been too lazy to cook before...
I am an extremely active person (10-12 hr/week doing Karate, 2-5 hr/week of additional training) now, and I can't imagine going back to feeling like that. Working out definitely improved my energy level -- mostly because it helps me sleep through the night.
One other thing: When I was having a particularly hard time with energy/feeling wiped out, even after the Taurine thing, I did a Ketogenic Diet for a while. I switched to a medical food called Axona, which essentially puts your body in a state of ketosis without requiring a severe diet change... my doctor didn't recommend continuing with it for more than a few months, but it got me out of a tough rut in terms of feeling awake/functional.
I hope you feel better soon,
drago
