So, I have two 5mg oxycodone, a few different kinds of adderall and also 9 1mg xanax. Is there a good way to combine any of these?

For the adderalls I have a few 12.5mg IR, a few 20mg IR and one 15mg xr. Also I'll be getting 500mg of etizoalam powder over the week..So there's also that.

I was planning on taking the two percs now and use the adderall and xanax throughout the week. Any other better ways to get a "better" high?
