Imo that depends. If you don't encounter any major issues in your life, then I'd skip the meds. Not only they're really expensive, they're also really difficult to get ( especially recently, for some reason they rarely appear in the pharmacies ). They also don't always work - this is most likely different for each person, but I feel that they provide only a slight boost in my concentration and motivation ( in my case though, this is does make a difference ).
