I really don't trust psychiatrists. But nevertheless, my psych told me today at an appointment I had with him, because I asked about vyvanse we had a discussion and he said something about it and I brought up stuff I had read on the internet-the conversion chart. That 70mg=22.5mg of d-amp.
Then he brought up a theory that he had brought up before and I wanted to know what you guys thought of it. He also said something I found kinda ridiculous and is (in my opinion) a good example of why not to trust psychiatrists. He said that he usually gives some people with ADHD vyvanse once in the morning and once before bed and they have the best night of sleep they've had in a long time....right.
But the theory was that I'm really just on 10mg of d-amp because thats the amount that's staying steady in my blood plasma levels or something like that. He said that because its 10mg IR I take it 3 times a day so I take it, it's active, I pee it out or whatever, take another, etc.
He said that with vyvanse it's 22.5mg steady in my blood plasma levels all day so its like taking 22.5mg three times a day...
this can't be correct can it? isn't 70mg vyvanse=22.5mg d-amp released throughout the day..?
 
All depends on the rate at which lisdexamfetamine is broken down in the blood into dextroamphetamine. But I do highly doubt the numbers are that nice. Probably a big spike about an hour after administration, and a slower tapering thereafter.
 
I just wanna make sure lol.
I know if I go on the vyvanse he won't wanna switch me back to dexedrine.
And honestly I'm curious about how he says that I'm only on 10mg. He said "Your only on ten milligrams of d-amp since you take it and it's out of your system and then you take it again-where as, while vyvanse may just be 22.5mg it's steady so it's like your taking 22.5mg three times a day."
i was curious about that because I thought 70mg vyvanse=22.5mg of d-amp total being slowly released throughout the day....
