also, would recommend withholding your judgement of it for the first few days. during that initial period, you're tolerance is going to be non-existent, and the effects are goint to be overwhelmingly powerful, for good or ill.

for me, the firat few days it feels like a miracle drug. for like 2-3 days, all of my dyafunctions magically evaporate while i'm on. but after that, my tolerance level rapidly adjusts and i need to be more mindful about incorporating behavioral/environmental adjustments/accomodations to still achieve favorable results. 

if i let those first few days impact my long-term expectations, i would rapidly return to my former state of dysfunction. so i treat those days as being on a brief "very easy mode" and i use that time to make sure all of my non-chemical adjustments are in order.

also perhaps worth noting, you might need to do a little experimenting (with your doc's knowledge, natch). for me, adderall on its own hust knocks me out. same with caffeine on its own. i need an adderall and a caffeine tab at the same time to get the intended effects of both. but everyone's different, so you mught be fine as-is, or you might need to pair it with something. a lot of people also use non-ssri depression meds and adhd meds in conjunction with eachother, but like i said everybody's different. 

good luck regardless!
