Every medication affects each individual differently. You will find positive and negative reviews of every ADHD medication, because the effectiveness depends on an individual’s specific neurotransmitter functioning, metabolism, and genetics.
There are two types of stimulants: amphetamine (Adderall, Vyvanse, Evekeo…) and methylphenidate (Ritalin, Concerta, Quillivant…). Almost everyone does well on one type or the other, but not both. Dexedrine is a dex-amphetamine, so it is a different type than what you’re taking.
Also, be sure you’re working with someone who specializes in ADHD, so that you’re working with a clinician that has a lot of experience with ADHD medications. They are prescribed very differently than most other medications.
