What do your Concerta pills look like? If they aren’t from Activis and don’t say “alza 54” on them (this is basically real Concerta sold as a generic), then they’re probably pretty much useless (and were/are under FDA investigation for not being equivalent). The one month I tried a different generic was the month I paid a hundred dollars for sugar pills (except for like two pills – those were like getting hit by a train), so now I will go to different pharmacies until I find the right kind.
So yeah, if you’ve not gotten the Activis stuff, make sure you actually experience Concerta before you write it off. But if you’ve been on the Activis stuff and it’s not working, then welp.
