vyvanse & benzos (valium)

[d1g1talflam3]

Hello, I just started taking 30mg vyvanse(lisdexamfetamine/prodrug version of dextroamphetamine xr) for 2 weeks which i would save up so i could take 90-150 mg every few days to achieve a speed high. Now im on 50mg(exual to 20mg d-amphetamine) daily which i take every morning (10-11am). I always take it and dont ever save it up anymore. I do abuse valium daily, i usually take between 20 to 40 mg a day in one dose. I have a few questions:

- Is this dangerous?

- When i take the valium (usually around 3 or 4pm i take between 20 to 40 regularily (sometimes 50 to 70) and when i take it i only seem to get the relaxed/drunk feeling for like 1 or 2 hours. While iv read that valium effects last 6-8 hours?

- Will either cancel the other out?

- I am also a cocaine addict (weeks sober) if i was to do coke again while on these drugs, would there be any bad/good side effects?

Any answers or opinyons widely appreciated!

Taking too much of any amphetamine can't be good on the heart. Benzos don't cancel out the effects of amps and you presumably already know this. If you're asking if the combo will make your heart jump up and down really fast to slow, no it won't.

Benzos tend to dull the amphetamine experience for some people.

Abusing benzos is not good. Addiction to benzos is highly undesirable.

Thank you, and what about if i was to do coke while taking 50mg vyvanse each morning(Its only 20mg d-amp spread out over like 10 hours?

and is it normal to only feel high on valium 30-70mg for only 1 or 2 hours, an hour after i take it? I thought it was a 6-8 hour high.
