If you have ADD and have side-effects from higher dosages, then FORGET about the idea that it's dopamine-tolerance we're talking about: you may have SCT - Sluggish Cognitive Tempo - those of us with this disorder receives even LESS cognitive improvements from those drugs, even at therapeutic dosages, than even normal people!
That's because SCT is a disease of Norepinephrine/Noradrenaline, and NOT DOPAMINE!
Stimulants, at least Amphetamine and Methylphenidate, are both, for whatever reason, more selective towards Norepinephrine in smaller dosages - hence the pattern of SCT-ers using only small dosages of stimulants.
Apologies if this post sounds aggressive, but I don't want you to make any stupid mistakes, especially not of the variety I did - i.e, spending too much time trying to get stimulants to work, when they were never going to work. All it'll lead to, is depression and anxiety.
You can read more about SCT here, and determine if it sounds like a good fit for your symptoms:

And in these links you can read a bit about stimulants and NE:
Treatment of adults with attention-deficit/hyperactivity disorder

Methylphenidate in low doses, also enhances hippocampal norepinephrine efflux but does not seem to affect dopamine in the nucleus accumbens. The data are consistent with the hypothesis that enhanced noradrenergic neurotransmission, particularly in the prefrontal cortex, contributes to the effects of methylphenidate

(the above study even shows that at low dosages, stimulants can actually cause auto-receptor down-regulation of dopaminergic neurotransmission - which seems to fly in the face of people receiving helpful increases of DA from LOW dosages - obviously not...)
Thank you very much, I will take a look.
Don't understand it wrong, but I want to skip that now and return to the main question: Does DXM help in low doses (with dopamin tolerance)?
PS: I didn't introduced me fully, because I don't have enough time yet. I have a official adhd diagnosis with some complex and specific abnormalities (I can't explain it now, but I can give you some bullet points: adhd-PI, depressive behaviour (not depression as a disorder), high IQ and dramatical underachievment and mainly motivational problems= I never learned to learn). I can only reach my full potential, when I'm high as fuck...because, I never had the urge, to achieve etc.). My situation now is like a ADHD-disorder, which is my fault (partly)...but the differences between what I could do, and how I can perform now is so fu**ing big, that even my doctor was surprised and interested in...
PS: The reason, why I take only small dosages now, is, that I build a tolerance over 6 months, which leads (for what reason ever) to more side-effects.
Also my physical state isn't that well now...
I was able, to take 60 or whatever in a day WITHOUT the physical side-effects, I NOW have....this is what wonders me: the side-effects were non-existent in the beginning and appeard LATER (after 2-3 months of use)...the side-effects are: physical and mental exhaustion, sleepiness, depression.
The small dosage is effective, but I only take, because there is nothing effective what I can take now...
I will explain my situation later, when I have time, but now, you have just to trust me, that I'm not going the wrong way...so, let's get back to the main question:
Have someone here tried DXM in very small doses for tolerance reduction? Will the NMDA antagonist damage of DXM occurs in low dosages (in comparison to memantine, amantadine, it blocks the whole nmda, that is what it make so toxic(?))?
I imagine something like 10mg before bed for ~1 week in a row...how much would be the cost/use proportion
PS: SORRY for my bad english and my bad formation, I have very less time and I normally, I don't like to write/talk about stuff, where I could say more deeply, but can't, because of time issues...
