My first thought is it's just another case of pre-diabetes. People who suffer mysterious conditions like to hypothesize and post their theories here about complex. thermo-dynamically impossible interactions between their various drugs and supplements as the source, and want to know which drugs they should add to the mix.
I briefly worked with a woman whose lunch every day was one of those giant Starbucks things with whipped cream--basically an extremely caffeinated ice cream sundae. She slurped that down at 11am, and then around 4pm every day she'd start bitching about a pounding headache, stomach aches, and low energy (better get another coffee drink!). She could not understand what was happening to her, and probably blamed it on gluten inhibiting CYP2D6.
For viewers at home, keep in mind these stims raise your blood sugar and suppress appetite, so you can double-crash when they wear off. The blood sugar rise in diabetics like me is substantial--as long as there's glycogen or muscle tissue to break down. So before you hypothesize mysterious workings of your brain receptors, consider re-working your lunchtime.
Now, back to OP, who remains unstuck in time, occupying all time qualifiers at once, always returning to the Dresden/selegiline firebombing.

to feel some negative effects during and after both when it is working and in the afternoon too.
Effects occur during AND after. When it is working, AND in the afternoon (but that's when you like it, that 3-4 hours in the afternoon), and it works for 14 hours, but you can't subtract 14 from your bedtime to avoid insomnia.

I never felt a crash when either it wore off or even any comedown in The evening.
Thank you for clarifying the differences. Which one includes insomnia?
This feeling is oddly amplified when I have just eaten, or even drank water, or I am hungry
I'd say that is finally some evidence that a piece of selegilne really is still stuck in your brain, if only I knew how you felt when you're thirsty. Remember--acid pee is a problem, and you were taking megadoses--which are a full 10^12 greater than microdoses--of vitamin C. There's nothing in nature to explain a microdose having different effects than a normal dose, but megadoses (of megadoses--teradoses!) are well to know to cause new functionalities like death.
The critical period for ascorbic acidosis buildup is thirteen days. Fortunately we don't know exactly how long it's been. That gives us some protection from damage to your bladder.
