Yeah basically Vyvanse (or lisdexamphetamine) is a 100% pure dextro-isomer of amphetamine (as opposed to Adderall which is 75% Dextroamphetamine and 25% Levoamphetamine), but it's coupled to an amino acid Lysine which makes it so that it's inactive until the Lysine is split from the Dextroamphetamine in the body.
Adderall XR costs approximately $760 per 100 capsules ($7.60 per capsule)13, and the generic version is available for $465-$533 for 100 capsules (from $4.65 per capsule)14. It's more subtle, and that subtlety definitely gives it a more therapeutic vs recreational subjective experience.
Still, the length of effectiveness with Vyvanse is hard to beat. Even though they are medications for ADHD, people often misuse these drugs for leisure such as drinking on Adderall. Amphetamines for Attention Deficit Hyperactivity Disorder (ADHD) in adults. I have taken slightly more than prescribed doses of Vyvanse, but at the end of the day, I always felt satisfied and slept like a baby. I can freely switch to a higher priority task at will. The levoamphetamine has less of a cognitive effect but usually more of the cardiovasculair and tweaky (and awake/alert) effects. Modafinil vs Adderall: What's the difference? I've been wondering if switching Vyvanse might be worth a try to see if that helps, and while I know meds affect everyone differently I do seem to be noticing a pattern in people's experiences where motivation issues are better dealt with by Vyvanse. Lisdexamfetamine is only available as Vyvanse, at a cost of $884 for 100 capsules ($8.84 per capsule).15 Don't hold your breath for a generic - one isn't expected until 2023!16, No. It helps me so much more than Vyvanse ever has that it’s not even a contest - it’s not even close. Your point would be relevant only if the different isomer ratio in Addy vs the effective d only in Vyvanse produced a huge difference in effects. This is just my opinion/experience with it so I don’t know how helpful it’ll be for you. New comments cannot be posted and votes cannot be cast. Strattera vs Adderall: What is the difference? Cellphone games, organizing things that needn't be, etc. Since Vyvanse needs to be converted in the body, it can't be inhaled or injected as a way to become high. Still, never tried Dexedrine, so it's hard for me to say for sure.
I was having raynauds phenomenon if anyone even thought cold thoughts nearby, and later in the day it was leaving me an anxious, irritable, shaky mess.
