Why is Vyvanse? UK based.

Vyvanse is like long acting adderall that cannot be crushed and snorted. Must be metabolized in your digestion to become active.

Thank you. Will ask my doctor.

Not to be confused with "Adderall XR", which like Vyvanse is meant for slower and longer release than normal Adderall.

At least for me, Vyvanse is much more tolerable than Adderall XR.

It's always extremely weird to me when people have to make this distinction because I was under the impression that ALL Adderall prescriptions are for the XR extended release which comes in capsules full of small beads of medication. No one should be taking Adderall IR instant release tablets. Those things have almost no reason to exist. I really don't understand who is taking those things and where people are getting the impression that IR tablets are a normal Adderall formulation. "Long acting" Adderall has been the norm for decades now and I haven't even seen or heard of anyone taking IR tablets since like the early 2000's

The XR mechanism is shit compared how vyvanse and concerts manage theirs.

If you’re a slow metaboliser you end up getting a big overlap around 3hours in which can be quite unpleasant, hence the non XR compound

If I take the lowest dose concerta I will not sleep that night no matter how early i take it. This was pretty devestating when I was younger and not mature enough to realize what was going on. Parents were obsessed with ADD medication at the time. I think vyvanse or xr adderall would be a similar nightmare for me.

Interesting.

I had similar issues with XR methylphenidate and Dex, but concerta and vyvanse were find if I took them first thing.

I suspect a bit insignificant amount of people are slow metabolisers and are having a shit run with stimulants as a result

Yes. Never tried the others. stratera - weird side effects quit immediately. ritalin is good. concerta also good... too good. Havent tried it in years Id only guess if anything Im slower if older.

I was given a prescription for XR. It took me a month or more to even try it, because I’d sleep in, then it would take me a while to get moving, and by that time I was worried it would still be active with the idealist it me would think I should go to bed. Something that didn’t last as long would give me much more control.

Because there is ritalin and concerta, I think it's just easier to understand and explain. Im less familiar with adderall but by searching a few times IR XR and Vyvanse are still prescribed? and adderall ir is also approved for narcolepsy at least.

Lisdexamfetamine, it’s very similar to Adderall but more expensive as it comes in capsules instead of tablets, but the upside is it lasts all day instead of a few hours. It recently became generic in the US, but is still around $60-120 a month’s supply (at least at my dosage), vs $25 or so for a month of Adderall.

Thank you.
