Combinations - adderell + diazapam = good idea?

[preacherreacher]

Has anybody ever taken diazapam with adderell? And what were the effects?

SWIM wants to remain anxiety free in social situations but needs to improve his powers of concentration, focus and logical thought, all of which that can be achieved from taking an adderell or a very low dosage of amphetamine but SWIM knows that taking an upper and a downer at the same time is quite possibly a bad idea and he had wondered if the side effects would outweigh the benefits.

Has anybody done this? SWIM is looking for actual experience rather than theory because he is well adversed in the theory but practical experience is often altogether a different matter matter and it is very hard to predict drug interactions on the body without real life cases.
