hi. amphetamines are...tricksy. people can adjust to them. sometimes...and im not saying this to scare you, it just..it is what it is, basically...sometimes, some people are prone to amphetamine psychosis, agitation, anxiety, crashes into depression, mood instability, etc.

it was once thought that psychosis from legally prescribed stimulants was rare...but it seems that its actually surprisingly common.

sorry about this. does it help lift your mood, at all? the tics...are they low level TD or pre-existing? i had ocd-related stuff that got better on amphetamines...and then when the doctor raised the dose, the ocd (complete with tics) got worse, and stayed that way for the duration of treatment. :-(

i dont have a solid answer, obviously. sedatives were once popular with amphetamines for this very reason. back then, it was barbiturates, now and then Equanil, sometimes low dose sedating antipsychotics. these days, I think low(er) potency benzodiazepines are sometimes used for the same purpose. personally...i found librium helped amphetamine stuff more than klonopin...but that's not the best long term solution, and it can make mood instability and amphetamine psychosis worse, not better, over the long haul.

just please be cautious. :-)
