You must go to a psychiatrist or psychopharmacologist. Your health insurance, referral from someone you know or local hospital should be able to guide you to one in your area.
The best thing to do is to go for an in depth mental evaluation. You don't want the stuff if you really do not suffer from ADD or ADHD, or other conditions a qualified Dr. sees fit for. Be careful there are a lot of quacks who are rx happy. A regular family Dr. can prescribe, but usually only after a diagnosis has been made by a psychiatrist.
That depends on the type of drug test being administered. It could show up for years on a hair test.
Ill be the first to tell anyone taking any drug of any kind an hour before a drug screen. No, its not possible for a urine test to show positive for that or any kind of drug that soon of time regardless of your metabolic rate. Unless that is your flushing your system out drinking glass upon glass but i suppose even at that time the test would show up as unconclusive being that much fluids are being pushed through your system to fast. But to answer your question again, No
It will probably do the opposite actually. adderall is contraindicated in people who have bipolar; basically that means if u have bipolar, dont take amphetamines. the risk of rapid cycling and an increased variation in mood is really high when taking adderall while having bipolar. if anger and irrational thinking accompany your bipolar disorder, stay away from adderall, as these two symptoms are common side effects from it. (especially in those with a preordained mental health condition or emotional lability).
