The ONLY way to know how it will react with your individual brain chemistry is to try it and find out.
Personally, I cannot take any ritaline family meds (concerta is methylphenidate), because they make me sick to my stomach whenever I get happy, and actively throwing up if I get excited. Ugh. Ick. No thanks!!
Does that happen to most? Nope. Just some. The same way that Adderall triggers "adderage" is some, but others are totally chill on it.
Since lisdexamphetamine worked GREAT for you, but made your heartrate go sky high, I'd try other amphetamine based meds first... To see if you just respond badly to the lisdexamphetamine, or if it's amphetamines in general that do a number on your heart. Adderall is a blend of short and long acting amphetamines, including dexamphetamine but NOT lisdex. Similarly, there's straight dexamphetamine options available as well.
Some people are ruled put of whole families of meds, others just need a slight chemical tweak within a family to find 'perfect'.
