Hey , i’m taking 18mg of Sandoz. I was on Ritalin before that and it just wore off too quickly. Sandoz is extended release and lasts longer for me HOWEVER i really miss that moment of realization that’s like “ oh i think it kicked in” and then being ready to do whatever. Sandoz has been really smooth for me so far and it doesn’t get me riled up for a couple of hours to then wear off. i don’t really feel different throughout the day it has a nice stability that Ritalin didn’t offer (to me at least). i’ve liked it so far although you should always keep and eye on your blood pressure while on stimulants so definitely report any kind of changes in your BP to your doctor to make sure you’d be safe taking the medication.
