Fake addys and legit Mexicos?

So I tried this adderall I got off the streets orange 30mg . So I took it in the afternoon and actually felt good. Like my mind wasn’t shooting 100 thoughts at once. (Side note I also drink around 300-600mg of caffeine almost daily as an appetite suppressant) Then I took a Mexico Xanax to help me sleep at night. Today was the second day repeating that. Now im 99% sure these are prob just meth and caffeine . So I’m trying to limit the addys to once or twice a week instead of just staying away from them completely. (Mainly cause I have zero appetite with them and I love that) but the bars really help with my panic attacks and insomnia so I wanna limit those to like every 2-3 days? Anyone have any incite on a similar situation of sorts? For reference I’m 5’2 / 300lbs / 26 female
