Yeah I thought it was depleted dopamine from amps which l-dopa should sort out, but it's not, my dopamine receptors are so downregulated my brain apparently decided to stop producing dopamine, ne, and adrenaline. Cause? After a bit of research it wasn't hard to find out what happened. Cathinones especially potent ones have a double action effect, both DRI and DRA and this results in such dopamine overload that your receptors just go poof. I have quit before you ask, but life has not been great...
