Vyvanse is a stimulant/amphetamine. Its exactly the same as adderall. All these stimulants are just "Legal cocaine" but stronger!!! Please-if you're considering trying any of these "ADHD" meds-DONT DO IT!!! Once you start you will never be the same. I have been physically dependent on adderall for 4 years now & trying that pill for the first time is the biggest regret of my life & I Would do anything to go back & change that because it has forever changed me psychologically I'm now diagnosed with Dissociative/depersonalization disorder, extreme depressive disorder, anxiety, panic attack disorder, manic depression, OCD, bipolar, & borderline personality disorder. Above all, this drug has consumed my life & stolen my identity. Read my forum in ADHD-"addicted to adderall". Think about it, theyre generically named "Amphetamine Salts" HELLOOO!!! Ring a bell?? Yepp, thats right, METHAMPHETAMINE. Adderall is the legal form of meth. Don't believe me? Look it up. Please please please get out while you still can & if you've never tried it-DO NOT! I know that everyone has a purpose in life, maybe this is mine-to save others from this "glamorized stimulant." I apologize for my strong emotions in this post (yepp, that's the adderall!) notice its 3AM?? I didn't! Point proven.
