On the flip side to addiction, my prescriber did not know or care what she was doing and when there was an Adderall shortage she gave me Vyvanse and said it "wasn't as effective" and almost tripled my dosage. I believed her but I basically became an addict to other things - social media, video games, spending, alcohol, porn because I was hyperstimulated all the time (being terminally alone did not help either). I am the type of person to say "oh this is just an onboarding phase, I'll wait and see" too which definitely contributed to it as well.
Thankfully, I am past that phase in my life but am still picking up the pieces. I am properly medicated now and the right combination of medications and care really does make a world of a difference.
