Hey OP, sounds like you’re going through the worst kind of hell that nobody would wish for or ask for
First off (I’m a male, 30) and have used Vyvanse, Adderall, and in my early 20s became fascinated with how ADHD and stimulants affect the brain and read a few books and went through a few documentaries on the subject
And while I don’t have ADHD, or regardless of whether or not you have ADHD, I don’t think anyone here will understand what you’re going through in terms of the massive dosage you were taking on a daily basis
Let’s see, a 6 month supply in 30 days? A regular dosage is what, 60mg a day?
If you were taking 30mg pills or 60 mg pills...the average user is prescribed 45 pills a month? 30 pills a month?
At 45 pills a month for 6 months thats 270 pills, and divided by 30 days that’s 9 pills a day
But okay getting back to the massive withdrawal symptoms on hand
You’re brain has 3 key receptors that control your mood, appetite, sleep, behavior, and other functions that are triggered by stimulants including ADHD medications
Those are: the dopamine receptor, the serotonin receptor, the norepinephrine receptor
But when you MASSIVELY overload these receptors, your brain isn’t able to recycle those chemicals needed to fuel the re-uptake process and naturally create and start the process over again
The literal shaking, inability to sleep, focus, eat, think, talk, or focus is absolutely destroyed in your brain right now
Best course of action: buy 5 HTP vitamins to help your brain calm down, and melatonin
Drink a shitload of cranberry juice and water for several days to flush out your system
If you have a job or school. You might not be able to get through everyday tasks for a while
The recovery time might be 2-4 weeks for a case like this
Try some Kratom, ingest a bunch of CBD pills, and know that this can and will get better with time and sleep
