> I thought section 2, the detailed analysis of the complex network of different brain structures and neurotransmitters impinging on sleep, might have made something click.It might have had I not gone in looking for something about the DA autoreceptors. :-) I'll have to look at it again but even if other things can impinge on sleep, it has to be related in some way here to what the selegiline does, no? Otherwise how is it relevant? Perhaps my first step is to read up on exactly what selegiline does once you consume it.

The sleepiness thingie is a side-effect, in the greater scheme of things.I think I have less of a problem with fatigue than with lack of motivation. (I get bouts of CFS when I'm run down but it's not all that often anymore.) I would be taking the selegiline for depression/motivation. Any other benefits would be gravy. Besides, the sleepiness thingie could be a side effect that is telling me what the nature of the problem is though.

> Yes, your brain could have adapted to a deficiency in dopamine by becoming exquisitely autoreceptive. But again, I'm encouraging you to not close your mind on the subject. Theories are just that, theories. What else might explain your symptoms/response to meds? That should always be something being thought about, in parallel to your consideration of this one theory.Most of the other theories I've entertained so far have to do with processes around dopamine in some way. Too limiting perhaps?

I suppose if it were the SSRIs there would be a lot more people out there reacting paradoxically to stimulants.
> > All I know is that I've had this for the past few months because over that time I've tried several stimulant type meds and supplements that have all, paradoxically, put me to sleep. I doubt it has gone away since my last recent trial but when I start on the selegiline again I will find that out. One thing I am certain of is that I will never know the answers to the questions of how long I've had this problem and what caused it.
>
> Have you stayed on the meds for long enough to see if your body re-adapts?No, that's why I've just started trying it again. It's not easy to function on it though because it makes me sleepy during the day and then 8-9 hours later makes me feel stimulated. I will probably try taking it at night and hope that taking the DLPA in the morning will work out. If I start to change how I react to it (which is the goal) then I would switch to taking it in the AM.
> > So the next step is to take measures to lessen the hypersensitivity. I think it makes sense to try the selegiline again with the DLPA this time as you have been urging. It's cheap, I tolerate it and I have all of the ingredients here at home already and if it works, I don't have to worry about the MAOI diet. My next questions to you now are:

In gut uptake, the drugs run an enzyme gauntlet in the intestinal wall and mesentery, and then pass via the portal vein to the liver, where they get another shot at being enzymatically transformed. It looks like selegiline is substantially affected by first-pass metabolism, so I see this as a pharmacological issue, not a political one.The selegiline citrate is a liquid - not sublingual. It goes through the stomach. So in that respect it would be a more equal comparison. Perhaps I will do the experiment at some point.
Have you given up on the selegiline yourself? The last I read it was bothering your asthma and creating GERD problems again. It's so frustrating when you find something that works but you have problems taking it.
Thanks again,
