Abilify is the best thing you can combine with adderall and vyvanse. Bupropion -I wouldn't use too much because it blocks
certain nicotinic acetylchole receptors which is undesirable and would have a negative impact... - is a good one, since it's a stimulant itself. It would potentiate other stimulants, but if it's amphetamines, the dosage would have to carefully be adjusted so it doesn't block the amphetamine from entering the cell via DAT and NET. If you can get methylphenidate, a low dose of that would also work.
There's also modafinil, a DRI and D2 partial agonist (like abilify - so it would enhance the effects while also preventing reuptake). I think modafinil would combine excellently with the meds you mentioned. It's controlled so it might be difficult to get, but you can buy adrafinil online which is the prodrug for modafinil, turning into it in your body - in essence it pretty much is modafinil.
Zoloft. I know it goes extremely well with methylphenidate. It had dopaminergic effects on its own so it's a good combo... Abilify is the best thing you can combine with adderall and vyvanse. I know it sounds strange - but since it's a dopamine type 2/3 partial agonist - it doesn't block the effect of amphetamines. It's been reported to greatly enhance them. The column on the left:

I was wondering if anybody has experienced combining Effexor with stimulants? Effexor is stimulant itself at certain doses, preventing the reuptake of serotonin, norepinephrine, and dopamine - at high doses and to a certain degree. I just know its damn stimulating on its own.
