Dexedrine/ Adderall dose comparison? | ADHD Information

My doc has switched my prescription from Dexedrine to Adderall XR(haven't started taking them yet) to see if it will work longer for me.

I've been taking 30mg of the Dexedrine Spansules in the am that works for around 6.5-7 hours then take 10mgs of the tabs 2x in the pm(I work 12hr+ days).

He's instructed me to take 15mg of the XR once or twice a day. My question is will 15-30mg of Adderall XR be an adequate dose when I was previously taking a total of 50mg of Dexedrine a day?
Distraction38713.2038541667 EEK, I would rather be on the dexedrine
 There is a XR version of dexedrine... the adderall is more $$$...

 It is probably very close to compare the two side by side.  One is 4 salts, one is two.

 I would poke around the net and see first...

I know it is a parent/teacher overview, but I found some information that might help.

I wanted to try the Adderall XR because the Dexedrine Spansules(time released) only lasts around 6hrs or so for me and I need something longer acting.

I decided to try the Adderall yesterday and I hated the stuff. I tried to take it slow. Like I said previously, I take a total of 50mg of dex a day using both the spansules and tabs. So I started low with the Adderall and took  1/15mg cap then waited 2 hrs. Nothing happened so I took another 15mg cap and waited another 1.5hrs. I noticed a very slight benefit but nothing great at all so took a third one(total 45mg). Big mistake. I suddenly had a rapid irregular heart rate, major anxiety and felt light headed. Even after the Adderall XR wore off the anxiety and elevated heart rate last till I went to sleep lastnight. I then slept 10hrs!

I'm assuming it was the other amphetamine salts, not the dex as the dextroamphetamine never produces those reactions in me.
