Sorry but you don't get it. Your psychiatrist has not the scientific knowledge required, by far. He has never heard of any of the drug I mentioned and most of them are not officially prescribed for those uses anyway. For anxiety though at least in the U.S he could prescribe guanfacine, which improve both adhd and reduce anxiety. So yeah talk about guanfacine or else the inferior clonidine. Magnesium l threonate is a benign supplement you can buy online. Memantine is not benign but you can buy it online and find info on reddit. I don't advise the anxiolytics i mentioned for long chronic use although it's technically possible. Emoxypine though is good for health in general. As for Cialis the sex pill, well your psychiatrist will never wanna hear it but by canceling vasoconstriction it will reduce stim toxicity, not increase it. As i said zinc is worth a try but only if it allow reducing the stim dose. Again a benign supplement OTC. I would also consider alcar though less effective it helps reduce toxicity.
