In case anyone hasn't said it already, "pregabalin" ("Lyrica") or its cousin; generic-type "neurontin" (Generic as "Gabapentin") works if you just don't have "Lyrica" and you happen to have a supply of neurontin on hand, as I have a supply that has sat on the shelves for the past 4 years more or less, and if I didn't have a stupidly large amount of pregabalin/Lyrica in 300mg tablets with 3 and a half of the 100 count bottles I would most definitely grab some gabapentin/neurontin as a 2nd tier choice, though pregabalin has a hell of a lot less "drunk +1" type side effects, even at high doses (tested it at 6000mg+ and not much residual), and after you are able to kill your amphetamine high you will be treated to a great night's sleep that is like barbiturate sleep in that it is something that unfortunately seems a bit too instant from when you pass out too when you wake up! This would probably be my like 3rd choice past bensodiasepenes and any other depressant on hand, like methadone, something I have "tamed" many "spin sessions" with over the years I have been luckily given it by my PCP. Just thought those obvious two would have already been mentioned as well as anti-psychotics, which will do the trick if they are specifically dopamine antagonists.
EDIT: Basically for the scimmers.... Pregabalin/Lyrica----Gabapentin/Neurontin
