I take 10mg, twice a day. The effect average is 4 hours. The half-life is 8 hours. So it's wise to not take any at least 8 hours before you plan on sleeping.

Yes; Vyvanse is a prodrug for dextroamphetamine. Vyvanse contains a bonded chemical containing dextroamphetamine and l-lysine.
Dexamphetamine is short for Dextroamphetamine. The prefix "dextro" just defines the 3D configuration of the amphetamine molecule. Adderall is made of 50% dextroamphetamine salts. The other half of Adderall is whats called "racemic" amphetamine salts, which is 1/2 dextroamphetamine (the other 1/2 is called "levoemphetamine"). So, since 1/2 of the racemic half is actually dextroamphetamine, Adderall is composed of about 75% dextroamphetamine salts.
