Dextro .45

Well put....The biggest difference between meth and dextroamphetamine is the lack of SERT agonism and the presence of increased norepinephrine. Meth is less stimulating in therapeutic dose ranges, but the serotonin release from higher dose use (I believe over 25 or 30mg) blends with the dopaminergic effects to create a unique euphoria which is less self-limiting. The norepinephrine released by dextro/levo-amphetamine (and vyvanse which becomes dextroamphetamine) increases stuff like muscle tension and likely leading to that wired/jittery feeling.
That said, continuing with the vyvanse while also being on the desvenla will probably be broadly enough to land the plane, but it will not feel as smooth as meth.
If you can trust yourself with a small amount of oral methamphetamine concurrent with your vyvanse, it could be helpful, but I would only do this if you have a solid plan and failsafe to prevent lapsing back into ongoing use.
If you can also utilize N-Acetyl Cystine, that may help with compulsivity and urge to continue to use stimulants.
What's your ultimate goal here? Will you continue to be able to access the vyvanse for a period of time and taper down?
Unfortunately for the poster....they don't reside in Canada
There is a vendor who has damn near pharmaceutical grade 4-MMC (Mephedrone)
4-Methyl-Meth Cathinone HCL
500% increase in Dopamine
900% increase in Serotonin
Very subtle in low therapeutic doses, with robust mood-boosting properties. Euphoric & pleasurable.
Only ships within Cananda ....no customs to clear, shipped right to your front door XpressPost.
Perhaps not the best route considering your Methamphetamine dependence & withdrawal....but paired with your Vyvanse (Lisdexamfetamine) 3h onset / 10h duration the 4-MMC would give you the required SERT/DAT to taper off gradually
Minimizing mental depression & cognitive impaired and other unpleasant symptoms
But perhaps just Vyvanse is best? Your CNS will gradually go back to "normal"
I was on Vyvanse for a while....decent I guess. I strongly prefer the rapid acting Ritalin (Methylphenidate) 3-4h duration
Perhaps Vyvanse + Lyrica (Pregabalin) 300mg would be more comfortable as your taper
Good luck with the taper
