Vyvanse contains less amphetamine milligram for milligram, but that's offset by better absorption and higher doses. It's also all the same form, which works better for some people.
What you describe can be mostly from physical stress of being stimulated all day. Dexedrine, Vyvanse, or methylphenidate might give you a better ratio of cognitive to physical effects. Supplementing with a non-stimulant medication might help with your symptoms in the evening and also let you take a lower dose of amphetamine during the day. There's evidence that some supplements, like magnesium, can reduce adverse effects from stimulants. You probably already know this, but it's important to eat enough throughout the day and often hard to do that.
Thanks for the information, much appreciated! I'm afraid to speak with a psych cause they will take me off these meds that I rely on to perform neurotypically. Ritalin made me bipolar with severe mood swings. Wellbutrin paradoxically made me feel depressed. Only amps have allowed my brain fog to subside and slow down my racing thoughts.
Magnesium is great, I take it throughout the day. L-theanine helps with the come down as well.
