Does someone need my help for getting a drug addiction and promoting their mental illness? I'm here to help.
>first, what do I tell my psychiatrist to get her to give me vyvanse for it.
Vyvanse is for ADD/ADHD, so you need to convince her you have that.
Generally they start with the shitty non-stimulant options first and see if that works - which rarely help ADD, but certainly don't help hunger. If this happens, what you do is get the prescription but don't take it, then read the side effects, and say it doesn't work and that you are getting a few of the shitty side effects (pick the common mild but annoying ones people complain about on the internet).
Next, you might get into the real stimulants, which is more trial and error. Adderall IR was my favorite, Vyvanse wasn't bad, Ritalin made me a zombie.. they are all terrible for you. I eventually quit because long term stimulant use you'll find all kinds of problems that aren't immediately apparent.
In my opinion you ultimately want Adderall IR. Doctors like to prescribe stuff like Vyvanse (amp prodrug) because they think it has less potential for abuse (it doesn't), and ER amps because you take them less, but to me the control and immediacy of Adderall IR was the way to go. At my height I took between 60-80mg of IR per day. When I was on Vyvanse I took a 100mg I think, and a few times I tried 140mg but that made my heart race.
Remember that psychiatrists are easy to fool, you just need to know the right things to say. Doing careful research and acting stupid you can lead them to give you whatever you want. Even the good ones. You have to play the long game though, don't go in there asking for Vyvanse, go in there complaining about concentration and how it is affecting your life, but don't oversell. And remember, they'll likely push some bullshit drugs for a little while, so just don't take them, and report back the poor results ... leading you to what you actually want.
