how long have you been clean?

even heavy methamphetamine addicts are able to regrow their dopamine neurons. It can take a couple years though but it happens, it will. it’s not irreversible!

The best thing to do to increase dopamine neurons is specifically cardio exercise. it sucks but it regrows dopamine receptors. Other things that help are to avoid eating sugar, since sugar increases serotonin which decreases dopamine. Sugar also decreases testosterone. I also recommend magnesium and agmatine which upregulate dopamine receptors. Lastly, honestly psychedelics can be useful if used with intention, IMHO. They increase neurogenesis more consistently than anything other than exercise and fasting but are not for everyone, so if your not in the place to use them, don’t.
