I noticed that different brands of espresso coffee have different effect on my nervous system. Some are really good in the sense that they wake me up and make me feel fresh and dynamic, while others do nothing, and others make me really jumpy and nervous and stressed.
Why is that? I am not good in chemistry but is it because the caffeine molecule has many types of isomers? (structural and or stereoisomers) and each caffeine isomer affect my nervous system in a different way?
