I've read countless threads about this subject. But I have just one more question.

How long does Dexedrine IR last compared to Adderall IR?

What about Dexdrine spansules?

Geesh. No answers. I guess as advertised, 5 hrs. Or less, depending on person. And dex 3-4 hrs.... :confused::confused::confused::confused:

End of thread.

Adderall IR lasts 3, maybe 4 hours. Dex is shorter than that.

It seems to be different answers everywhere on the Internet. I guess it depends on the person.

I just have to take the chance and try it. The Adderall just isn't smooth enough.

Adderall IR lasts 3, maybe 4 hours. Dex is shorter than that.

Does it really? XR only lasts for 4 hours for me. I'm thinking about switching to IR (might've as well, right?).

It does for me! XR lasts much longer than 4 hours for me though. IR is much more of a roller coaster ride. There are lots of side effects from the ups and downs.
